7^{5 x + 7} = 2

x = \frac{ln ( 2 ) - 7 ln ( 7 )}{5 ln ( 7 )}

Solution steps

7^{5 x + 7} = 2

Apply exponent rules

(5 x + 7) ln (7) = ln (2)

Solve

(5 x + 7) ln (7) = ln (2) : x = \frac{ln ( 2 ) - 7 ln ( 7 )}{5 ln ( 7 )}

x = \frac{ln ( 2 ) - 7 ln ( 7 )}{5 ln ( 7 )}

20 (7^{2 x}) = 40 (5^{(3 x + 1)})

2^{2 x + 3} = 8

x, e^{r x} = 0

e^{9 - 4 x} = 8

e^{3 x} = ln (4)
