What is the cube root of w ?

we only need value of w to solve this one

(1) The 5th root of w is 64.

w= 64^5 SUFF

(2) The 15th root of w is 4.

w= 4^15 SUFF

BTW in both cases the cube root would be an ineteger only

coz if we express 64 & 4 in powers of 2, then it would result in an exponent that is a multiple of 3
