Answer 2

Answer:

$given \\ {3}^{x - 1} = 9 \\ = > {3}^{x - 1} = {3}^{2} \\ = > x - 1 = 2 \\ = > x = 3 \\ now \\ = > {4}^{y + 2} = 64 \\ = > {2}^{2y + 4} = {2}^{6} \\ = > 2y + 4 = 6 \\ = > 2y = 6 - 2 \\ = > 2y = 2 \\ = > y = 1 \\ now \: puting \: the \: value \: of \: x \: and \: y \: in \: given \: equation \\ = > \frac{x}{y} - \frac{y}{x} \\ = \frac{3}{1} - \frac{1}{3} \\ = \frac{9 - 1}{3} \\ = \frac{8}{3}$
