Question

please answer it properly

Answer 1

${ \frac{49}{36} }^{ \frac{ - 3}{2} } \\ \\ = { {( \frac{7}{6} )}^{2} }^{ \frac{ - 3}{2} } \\ \\ = { (\frac{7}{6}) }^{(2)( \frac{ - 3}{2}) } \\ \\ = {( \frac{7}{6}) }^{ -3 } \\ \\ = {( \frac{6}{7} )}^{3} \\ \\ = \frac{6 \times 6 \times 6}{7 \times 7 \times 7} \\ \\ = \frac{216}{343}$

Answer 2

(7/6)2*-3/2
cancel 2 we get (7/6)^-3
6/7^3
216/343
