I'm going to make a wild guess that you are trying to check an answer you got with the answer in the back of the book. I'm also going to assume that you were supposed to take a derivative of
(x^3/(a-x))^(1/2).
In that case, you got the wrong answer because you didn't do the chain rule. You still need to multiply what you have by the derivative of the thing inside, i.e. the derivative of x^3/(a-x).

If I'm making a bad assumption and this didn't come from a differentiation problem, please ignore my answer.

1/2x(x/(a - x))^(1/2) which is not much simpler.

well since E=MCsquared them the answer is obviously 7.5423780581947692

(1/2)(x^3/(a - x))^(-1/2)
(1/2)((a - x)/(x^3))^(1/2)
(sqrt(a - x))/(2sqrt(x^3))
(sqrt(a - x))/(sqrt(4x^3))
multiply top and bottom by sqrt(4x^3)
(sqrt((4x^3)(a - x)))/(4x^3)
(sqrt((4x^2)(x(a - x)))/(4x^3)
(2xsqrt(ax - x^2))/((2x)(x^2))

ANS : (sqrt(ax - x^2))/(x^2)
