Question

{-3/5}
{3/5}
{6/5}
{1}
{-6/5}

Answer 1

Explicação passo-a-passo:

2^2x+1 . 4^3x+1 = 8^x-1

2^2x+1 . (2²)^3x+1 = (2³)^x-1

2^2x+1 . 2^6x +2 = 2^3x-3

2^ 2x+1 + 6x+2 = 2^3x -3

Cancelar a base igual no caso o 2

2x +1 +6x +2 = 3x -3

8x +3 = 3x -3

8x -3x = -3 -3

5x = -6

x= -6/5

S = { -6/5}
