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!
