Answer 1

Question :-

$if \: ( \frac{p}{q}) = ( \frac{ - 4}{9})^{20} \div ( \frac{ - 4}{9}) ^{18}, \\ \\ find \: \: the \: \: value \: \: of \: ( \frac{p}{q})^{2} .$

solution :-

$if \: ( \frac{p}{q}) = ( \frac{ - 4}{9})^{20} \div ( \frac{ - 4}{9}) ^{18} \\ \\ ⟹ ( \frac{ - 4}{9}^{20} ) \div ( \frac{ - 4}{9})^{18} \\ \\ ⟹ ( \frac{ - 4}{9})^{20 - 18} \\ \\ ⟹ ( \frac{ - 4}{9})^{2}$

$now \: \: the \: \: value \: \: of \: ( \frac{p}{q} )^{2} \\ \ ⟹ (\frac{ - 4}{9})^{2} \ \\ \\ ⟹ \frac{16}{81}$
