18^{x^2+4x+4}=18^{9x+18}

1 8^{x^{2} + 4 x + 4} = 1 8^{9 x + 18}

x = 7, x = - 2

Solution steps

1 8^{x^{2} + 4 x + 4} = 1 8^{9 x + 18}

Apply exponent rules

x^{2} + 4 x + 4 = 9 x + 18

Solve

x^{2} + 4 x + 4 = 9 x + 18 : x = 7, x = - 2

x = 7, x = - 2

9^{2 x - 1} = 2 7^{x}

89 = 1 5^{x}

3^{x - 1} = 20

3^{x - 4} = 2

6 4^{x} = 256
