Answer 1

a) 27/64

b) 343/1000

c) 81/121

Answer 2

$a) \: ( { - \frac{3}{4} })^{3} ={ - \frac{3}{4} } \times { - \frac{3}{4} } \times { - \frac{3}{4} } = - \frac{27}{64}$

$b) \: ( { \frac{7}{10} })^{3} = { \frac{7}{10} } \times { \frac{7}{10} } \times { \frac{7}{10} } = \frac{343}{1000}$

$c) \: ( { -\frac{9}{11} })^{2} = { \frac{9}{11} } \times { \frac{9}{11} } = \frac{81}{121}$
