(i) Prime factorisation of 64 = __2 x 2 x 2__ x __2 x 2 x 2__

∴ 3√64 = 2 x 2 = 4

(ii) Prime factorisation of 512 = __2 x 2 x 2__ x __2 x 2 x 2 __x __2 x 2 x 2__

∴ 3√512 = 2 x 2 x 2 = 8

(iii) Prime factorisation of 10648 = __2 x 2 x 2__ x __11 x 11 x 11__

∴ 3√10648 = 2 x 11 = 22

(iv) Prime factorisation of 27000 = __2 x 2 x 2__ x __3 x 3 x 3__ x __5 x 5 x 5__

∴ 3√27000 = 2 x 3 x 5 = 30

(v) Prime factorisation of 15625 = __5 x 5 x 5 __x __5 x 5 x 5__

∴ 3√15625 = 5 x 5 = 25
