Solving Square Root and Cubic Root Equations

How would we say this if converted to radical form?

• "Thirty-two to the three-fifths"

• "Fifth root of thirty-two raised to the third power"

• "Third root of thirty-two raised to the fifth power"

• "Quintic root of thirty-two raised to the fifth power"

• "Thirty-two and three-fifths"

Rewrite in rational exponent form

• 4^4/3

• 4^3/4

• 2^4/3

• 2^3/4

• Cannot because the cubic root of 4 is not an integer
