Question

((8/11)^2)^-5*(11/8)^-12​

Answer 1

Answer:

This question can be solved by using the laws of indices.

$(( { \frac{8}{11} })^{2}) ^{ - 5} \times ( { \frac{11}{8} })^{ - 12}$

$= (\frac{8}{11} ) ^{ - 10} \times (\frac{8}{11} ) {}^{ 12}$

$= ( \frac{8}{11} ) {}^{ - 10 + 12}$

$= (\frac{8}{11} ) {}^{2}$

$= (0.72 {})^{2}$

$= 0.5184 \: or \: 0.52$

I hope you got your answer. But to answer these type of questions first you should know and study the laws of indices.

Thankyou.
