`sqrt(x^3)sqrt(x+4)`

Multiply the expressions under the radicand.

`sqrt((x^3)(x+4))`

Factor the radicand to find the perfect roots.

`sqrt((x)(x)(x)(x+4))`

Remove the perfect square roots from the radicand. Here remove the `x` because it is a perfect square.

 This leaves the solution which is:

`xsqrt(x(x+4))`
