9^{x - 1} = 4^{2 x}

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

Solution steps

9^{x - 1} = 4^{2 x}

Apply exponent rules

(x - 1) ln (9) = 2 x ln (4)

Solve

(x - 1) ln (9) = 2 x ln (4) : x = \frac{ln ( 3 )}{ln ( 3 ) - 2 ln ( 2 )}

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

\frac{15}{e ^{2 x}} = 3

3^{2 x + 1} = 27

4^{2 x + 1} = 4

2^{n + 1} = 32

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