#4*(x^2)^(1/2)#

Explanation:

The actual answer is just #4x# when simplified.

When something is squared then you write it as to the power of #1/2#. You can also write any root to the power of a fraction.

For example, #sqrt(3^3)# would be written as #(3^3)^(1/2)#. When writing the root of a number that is already raised to another power, for example #root(5)(3^3)# then it can be written as #3^(3/5)#. The denominator of the fraction is the root and the numerator is the power the number is raised to.

Hope this helps!
