9^{x^2+2}=27^{-3x}

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

x = - \frac{1}{2}, x = - 4

Decimal Notation

x = - 0.5, x = - 4

Solution steps

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

Apply exponent rules

2 (x^{2} + 2) = - 9 x

Solve

2 (x^{2} + 2) = - 9 x : x = - \frac{1}{2}, x = - 4

x = - \frac{1}{2}, x = - 4

3^{5 x + 3} = 15

625 = 5^{x}

0.2 = 48 + 48 e^{- \frac{1}{1200} x}

2^{x + 5} = 128

4^{x + 0.5} - 17 \cdot 2^{x} + 8 = 0
