8^{- 2 - x} = 431

x = - \frac{ln ( 431 ) + 6 ln ( 2 )}{3 ln ( 2 )}

Solution steps

8^{- 2 - x} = 431

Apply exponent rules

(- 2 - x) ln (8) = ln (431)

Solve

(- 2 - x) ln (8) = ln (431) : x = - \frac{ln ( 431 ) + 6 ln ( 2 )}{3 ln ( 2 )}

x = - \frac{ln ( 431 ) + 6 ln ( 2 )}{3 ln ( 2 )}

6^{x + 3} = 3^{x}

0.5 \cdot 1 0^{8 t} = 73

4^{x} = 6^{1 - x}

5^{3 x + 2} + 3 \cdot 5^{6 x + 2} - 100 = 0

3^{5 x + 2} = 21
