Solution steps

8^{x} - 10 = 9

Move

10

to the right side

8^{x} = 19

Apply exponent rules

x ln (8) = ln (19)

Solve

x ln (8) = ln (19) : x = \frac{ln ( 19 )}{3 ln ( 2 )}

x = \frac{ln ( 19 )}{3 ln ( 2 )}

x, f = C b^{x}

y, x = 4 e^{y} + y - 7

3^{3 x - 4} = 21

3^{3 x - 4} = 24

3 = 20 (\frac{1}{2})^{2 x}
