x = - 2

Popular Examples

9^{x+1}0.27^{x+2}=81^{x+3}

9^{x + 1} 0.2 7^{x + 2} = 8 1^{x + 3}

7^x+7^{x+2}=-2051+7^{x+3}

7^{x} + 7^{x + 2} = - 2051 + 7^{x + 3}

27^x(9^{2x-1})=3^{x+4}

2 7^{x} (9^{2 x - 1}) = 3^{x + 4}

2^{8x+3}=sqrt(2)

2^{8 x + 3} = 2

(27)/(9^x)=3^{x-1}

\frac{27}{9 ^{x}} = 3^{x - 1}
