Question

if P by Q = 3 by 2 to the power minus 2 / 6 by 5 to the power zero then what is the value of P by Q to the power minus 2?

Answer 1

$\frac{p}{q} = ( { \frac{3}{2} })^{ - 2} \div ({ \frac{6}{5} })^{0} \\ or. \: \frac{p}{q} = ( { \frac{3}{2} })^{ - 2} \\ or. \: ({ \frac{p}{q} )}^{ - 2} = { (({ \frac{3}{2} })^{ - 2} })^{ - 2} = ({ \frac{3}{2} }) ^{4} = \frac{81}{16}$
so option (d) is the right answer
