Find:

<

(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
