Question

Evaluate the following
$\frac{{\left(\frac{12}{13}\right)}^5\times \left(\frac{-1}{3}\right)}{\frac{1}{81}\times {\left(\frac{12}{13}\right)}^3}$

Answer 1

Evaluating given problem using law of eponents,

$⟹\frac{(12{)}^5\times (-1)\times 81\times (13{)}^5}{(13{)}^3\times 3\times (12{)}^3}$

$=\frac{(12{)}^2\times (-1)\times 81\times (13{)}^2}{3}$

$=144\times (-1)\times 27\times 169$

$=-657072$
