Question

Find: (i) 64 $\frac{1}{2}$ (ii) 32 $\frac{1}{2}$ (iii) 125 $\frac{1}{3}$

Answer 1

(i) 64 $\frac{1}{2}$ = (8)2 $\frac{1}{2}$

= 8

(ii) 32 $\frac{1}{5}$ = (2 × 2 × 2 × 2 × 2) $\frac{1}{5}$ = (25) = (25) $\frac{1}{5}$

= 2

(iii) 125$\frac{1}{3}$ = (5 × 5 × 5) $\frac{1}{3}$= 53 $(\frac{1}{3})$

= 5
