Boa noite
4^x * 8^(x + 1) * 16^(x + 2) = 32^(x + 3)
2^(2x) * 2^(3x + 3) * 2^(4x + 8) = 2^(5x + 15)
2x + 3x + 3 + 4x + 8 = 5x + 15
9x + 11 = 5x + 15
4x = 4
x = 1
4^x * 8^(x + 1) * 16^(x + 2) = 32^(x + 3)
2^(2x) * 2^(3x + 3) * 2^(4x + 8) = 2^(5x + 15)
2x + 3x + 3 + 4x + 8 = 5x + 15
9x + 11 = 5x + 15
4x = 4
x = 1
