Question

два уровнения срочно

Answer 1

(1/5)^(3-2x) = 5^3
5^(-3+2x) = 5^3
-3+2x = 3
x = 3

(1/3)^(4-2x) = 3^2
(3)^(-4+2x) = 3^2
-4+2x=2
x = 3

Answer 2

$( \frac{1}{5})^{3 - 2x} = 125 \\ {5}^{2x - 3} = {5}^{3} \\ 2x - 3 = 3 \\ 2x = 6 \\ x = 3$
$( { \frac{1}{3} })^{4 - 2x} = 9 \\ {3}^{2x - 4} = {3}^{2} \\ 2x - 4 = 2 \\ 2x = 6 \\ x = 3$
