Question

pls help me out to solve these 2 questions ​

Answer 1

Answer:

This is quite easy to do,

answers are accordingly find.

Answer 2

Step-by-step explanation:

${5}^{4x} \times {5}^{ - 2x} = 125 \times {5}^{x}$

${5}^{4x + ( - 2x)} = {5}^{3} \times {5}^{x}$

${5}^{2x} = {5}^{3 + x}$

Comparing both sides

2x = 3+x

2x-x = 3

x=3

22.

$\frac{x}{y} = (\frac{2}{3} )^{ - 2} \times (\frac{3}{5} )^{ - 2}$

$\frac{x}{y} = (\frac{3}{2} )^{ 2} \times (\frac{5}{3} )^{ 2}$

$\frac{x}{y} = \frac{9}{4} \times (\frac{25}{9} )$

$\frac{x}{y} = \frac{25}{4}$

$( \frac{x}{y})^{1} = \frac{25}{4}$

$( \frac{y}{x})^{ - 1} = \frac{25}{4}$

HOPE YOU GET IT WELL....
