Answer 2

Answer:

(i)

${( - \frac{3}{4} )}^{3} = - \frac{3}{4} \times (- \frac{3}{4} ) \times (- \frac{3}{4} ) \\ = \frac{9}{16} \times (- \frac{3}{4} ) \\ = - \frac{27}{64} \\ = rhs \\ hence \: verified$

(ii)

${( - \frac{2}{3} )}^{6} = - \frac{2}{3} \times (- \frac{2}{3} ) \times (- \frac{2}{3} ) \times (- \frac{2}{3} ) \times (- \frac{2}{3} ) \times (- \frac{2}{3} ) \\ = \frac{4}{9} \times \frac{4}{9} \times \frac{4}{9} \\ = \frac{16}{81} \times \frac{4}{9} \\ = \frac{64}{729} \\ = rhs \\ hence \: verified$
