tolong dibantu ya kak

5) (1/25)^(x - 2) = 5^(x - 4)
5^-2(x - 2) = 5^(x - 4)
-2(x - 2) = x - 4
-2x + 4 = x - 4
-2x - x = -4 - 4
-3x = -8
x = 8/3

6) ^3√25^(x + 4) = 125^(x + 1)
25^(x + 4)/3 = 125^(x + 1)
5^2(x + 4)/3 = 5^3(x + 1)
2(x + 4)/3 = 3(x + 1)
2(x + 4) = 9(x + 1)
2x + 8 = 9x + 9
2x - 9x = 9 - 8
-7x = 1
x = -1/7
