Question

if
$( \frac{p}{q} ) = ( \frac{3}{7} ) {}^{ - 2} \times ( \frac{2}{7} ) {}^{0} then \: find \: ( \frac{p}{q} ) {}^{ - 1}$
​

Answer 1

Answer:

Answer :-

$( \frac{p}{q} ) = ({ \frac{3}{7} })^{ - 2} \times ({ \frac{2}{7} })^{0}$

$(\frac{p}{q}) = ({ \frac{7}{3} })^{2} \times 1$

$(\frac{p}{q} ) = ( \frac{49}{9} )$

$({ \frac{p}{q} })^{ - 1} = \frac{9}{49} \: \: ans \: .$
