Answer :

(i) (64)1/2

Writing Prime factors of 64 we get that : 64 = 8 x 8

So, (64)1/2 = (26)1/2

(64 )1/2 = 23
            = 8


(ii) (32)1/5

Writing Prime Factors of 32 we get that: 32 = 2 x 2 x 2 x 2 x 2

So, 32 = 25 

(32)1/5 = (25)1/5

(32)1/5 = 2

(iii)(125)1/3

Writing Prime Factors of 125 we get that: 125 = 5 x 5 x 5

So, 125 = 5 3


(125)1/3 = (53)1/3

(125) 1/3 = 5


= 5
