the velocity time relationship of a body starting from rest is given by v=k^2t^{3/2}, here k=\frac{\sqrt{2}m^{1/2}}{s^{5/2}}

Let's put value of k in equation ,
v=2ms^{-5}t^{3/2}\\\\\frac{dx}{dt}=2ms^{-5}t^{3/2}\\\\\int{dx}=\int{2ms^{-5}t^{3/2}dt}
\int\limits^x_0{dx}=\int\limits^4_0{2ms^{-5}t^{3/2}dt}
x=\left[\begin{array}{c}\frac{2mt^{5/2}}{\frac{5}{2}s^5}\end{array}\right]^4_0
x=\frac{4m}{5s^5}(2)^5
