2^{9 x} = 5^{- x - 3}

x = - \frac{3 ln ( 5 )}{ln ( 2560 )}

Decimal Notation

x = - 0.61524 \dots

Solution steps

2^{9 x} = 5^{- x - 3}

Apply exponent rules

9 x ln (2) = (- x - 3) ln (5)

Solve

9 x ln (2) = (- x - 3) ln (5) : x = - \frac{3 ln ( 5 )}{ln ( 2560 )}

x = - \frac{3 ln ( 5 )}{ln ( 2560 )}

e^{x + 1} = 9^{\frac{2 x}{3}}

e^{- x} - 2 x e^{x} = 0

5^{x} + 5^{x + 1} = 750

(\frac{1}{8})^{x} = 1 6^{x - 3}

(0.5)^{x} = 2
