(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
