Describe how to transform into an expression with a rational exponent. (a index of 3, square root of x^4) raised to the 5th power

The answer is :x^20/3

Solution:
Simplify. ( cube root of x to the power of 4 )from the given :(a index of 3, square root of x^4) raised to the 5th power.
=x to the power of 4/3
multiply it by five will give you the answer of x to the power of 20/3
