Find: (i) 9 \(\frac{3}{2}\) (ii) 32 \(\frac{2}{5}\) (iii) 16 \(\frac{3}{4}\) (iv) 125 -\(\frac{1}{3}\)
(i) 9 \(\frac{3}{2}\) = (9 \(\frac{1}{2}\))3 \(\frac{1}{3}\)= (3)3 = 27
(ii) 32 \(\frac{2}{5}\) = (32 \(\frac{1}{5}\))2 = (2)2 = 4
(iii) 16 \(\frac{3}{4}\) = (16\(\frac{1}{4}\))3 = (2)3 = 8
(iv) 125 -\(\frac{1}{3}\) = \(\frac{1}{(125)}\frac{1}{3}\) = \(\frac{1}{5}\)
