Introduction
Nowadays, nonlinear fractional partial differential equations (FPDEs) are lengthily utilized to delimit several prodigies and dynamic procedure in numerous features of mathematical science and scheming, particularly in magnetohydrodynamics, neural material science liquid mechanics, dissemination process, numerical science, plasma material science, geo-optical filaments, strong state material science, and substance energy [1][2][3].
The prime goal of this article is to inspect the approached solutions of the nonlinear time fractional modified Kawahara equation in the form where δ denotes a parameter recitation fractional order of the time derivative constant and 0 < δ ≤ 1. Our preferred modified Kawahara equation (MKE) was previously measured by various investigators; for instance, Atangana et al. [39] planned the exact numerical solutions of time fractional mKE exhausting homotopy decomposition and the Sumudu transform strategy. Guner and Atik determined our stated time fractional MKE employing lengthy exp ð−φðξÞÞ-expansion approach [40]. Kadkhoda [43] to shape the detailed voyaging wave answers for nonlinear progression environments in scientific substantial science by means of the time fractional nonlinear mKE. The advanced exp ð−ϕðξÞÞ-expansion system is more regimented and steadfast system as compared to G′/G-expansion system. Our favored method is a parallel technique of G′/G-expansion process. The answers enlarged by the specified practice can be articulated in the form of hyperbolic, trigonometric, and rational functions. These events of the clarifications are appropriate for learning certain nonlinear physical dealing. The target of this article is to apply the advanced exp ð−ϕðξÞÞ-expansion strategy [43] to build the precise voyaging wave answers for nonlinear advancement conditions in scientific material science by means of the time fractional nonlinear modified Kawahara equations.
In contrast with the attained solutions [43], to the finest of our knowledge, antibright kink, bright kink, rogue wave, and bright and dark bell solution shapes are new in the case of our advanced exp ð−ϕðξÞÞ-expansion scheme, which are not testified in previously published studies [22][23][24][25][26]. It is important to know that the maximum of the examined solutions in this study has varied structures over the solutions accessible in the fiction in the wave proliferation; the performed approaches are entirely new for this studied mKE equation. Therefore, the developed exact answers may irradiate the authors for advance studies to clarify pragmatic phenomena in the field of shallow water wave and mathematical physics. This article affords evidence that our mentioned MKE equation is suitable in the sense of conformable derivative for obtaining the new traveling soliton structures in any kind of physical system without any obliqueness condition.
The study is set up as follows. In Section 2, the portrayal of the conformable derivative and scheme is deliberated. In Section 3, the advanced exp ð−ϕðξÞÞ-expansion approach has been described. In Section 4, we utilized this plan to the nonlinear modified Kawahara equations. In Section 5, results and discussion are presented. In Section 6, ends are given.

Meaning and Some Topographies of Conformable
Derivative. Recently, Khalil et al. [44] showed the basic of conformable derivative with the idea of a limit.
Definition 1. f : ð0,∞Þ ⟶ ℝ; then, the conformable derivative of f order δ is well-defined as Nearly, a famous researcher Abdeljawad [45] has also discovered exponential functions, chain rule, definite and indefinite integration by parts, Gronwall's inequality, Laplace transform, and Taylor power series expansions for conformable derivative in the process of fractional order. The definition of a conformable order derivative can naturally stun the difficulty of exiting the modified Riemann Liouville derivative definition [46] and the Caputo derivative [47]. Theorem 1. Let δ ∈ ð0, 1 and f = f ðtÞ, g = gðtÞ be δ-conformable differentiable at a point t > 0, then Theorem 2. Let f : ð0, δÞ ⟶ R be a real function such as f is differentiable and δ-conformable differentiable. Also, let g be a differentiable function well defined in the range of f . Then, where prime means the conventional derivatives with respect to t.
In this research, we have mainly taken the preferred equation with the sense of conformable derivative. In condition of general theory of calculus, there are numerous functions that do not have Taylor power arrangement representations on particular point whereas in the theory of conformable derivative they do have. The conformable derivative does well in the chain rule and product rule while involved plans appear in case of usual fractional calculus. The conformable derivative of a constant function is correspondent to zero where it is not the issue for Riemann fractional calculus. 2 Advances in Mathematical Physics

Enlargement of Advanced exp ð−ϕðξÞÞ -Expansion Method
In this part, we have deliberated our mentioned advanced exp ð−ϕðξÞÞ-expansion scheme stepwise in details. Assume a nonlinear time-fractional NPD equation in the following form: where Π = Πðx, tÞ is an anonymous function and R is the polynomial function of Π, it is a distinct kind of partial derivatives, in which the nonlinear terms and the highest order of derivatives are intricate.
Step 1. Now, we assume a wave transformation variable with a view to nondimensionality. We transform all selfgoverning variable into one variable, as follows By utilizing this variable, Equation (5) permits us reducing Equation (4) in an ODE for Πðx, tÞ = uðξÞ into the form Step 2. Let us assume that a polynomial can start the solution of O.D. Equation (6) in exp ð−ϕðξÞÞ as where N is the positive integer, which can be acquired by harmonizing the uppermost order of derivatives to the uppermost order nonlinear terms, seen in Equation (6).
And the derivative of ϕðξÞ gratifies the ODE in the subsequent form Then, the solutions of O.D. Equation (6) are as follows.
Step 3. By plugging Equation (7) in Equation (6) and consuming Equation (4), gathering all like the order of exp ð−mϕðξÞÞ, m = 0, ±1,±2,±3, ⋯ organized, then we accomplish a polynomial form exp ð−mϕðξÞÞ, and associating each coefficient of this obtained polynomial equivalent to zero yields a set of a system of algebraic equations (SAE).
Step 4. Let the constants' determination be obtained as one or more solutions by deciding the mathematical circumstances in phase 3. Plugging the constant calculations along with the arrangements for Equation (5), from the nonlinear evaluation eq., we can obtain modern and far-reaching detailed moving wave preparations (4).

Solicitation of the Preferred Method
In this subclass, we imposed our proposed advanced exp ð−ϕðξÞÞ-expansion technique in Equation (1) and henceforth used the following transformation: where k and Λ are nonzero constants. We find the ODE from Equation (1) −Λu′ + ku 2 u′ + Φk 2 u′′ + Ψk 3 u′′′ = 0: Now, we integrate Equation (14) with respect to ξ and we get where prime signifies the derivative with regard to ξ. Now, we calculate the equilibrium number of Equation (15) between the linear term u ′ ′ and the nonlinear term u 3 which is m equal to 1 so the solution Equation (15) Differential Equation (16) with respect to ξ and substituting the value of u, u′, u′′ into Equation (15) and connecting the coefficients of e iφðξÞ correspondent to zero, where i = 0, ±1,±2, ⋯.
Resolving those SAE, we achieve one set of solutions as follows.
Case 1: when λμ < 0, we get following solutions of hyperbolic type. Segment 1 Segment 2 where k = ± ffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffi ffi −ð1/36λμÞ Likewise, when μ = 0, the executing value of A 1 is undefined. So the solution cannot be obtained. So this case can also be excluded.
