64^(1/3) = 4

Explanation:

64^(1/3) = root3(64)

When finding roots of integers it is often helpful to express the integer as its prime factors.

64 = 2xx2xx2xx2xx2xx2

:. root3(64) =root3(2xx2xx2xx2xx2xx2)

We can now take each triple through the root one time.

:. root3(64) = 2xx2 = 4

Hence, 64^(1/3) = 4
