(0,125) pangkat x+4 = (0,0625) pangkat 2x+1

Exponent Equation.

0,125^(x + 4) = 0,0625^(2x + 1)
(1/8)^(x + 4) = (1/16)^(2x + 1)
(2⁻³)^(x + 4) = (2⁻⁴)^(2x + 1)
-3(x + 4) = -4(2x + 1)
x = 1,6

(0,125)^x+4 = (0,0625)^2x+1
(1/8)^x+4 = (1/16)^2x+1
8^-x-4 = 16^-2x-1
2^3(-x-4) = 2^4(-2x - 1)
2^-3x-12 = 2^-8x-4
-3x - 12 = -8x - 4
-3x + 8x = -4 + 12
5x = 8
x = 8/5
x = 1,6
