2 (3^{4 x - 5}) = 7^{2 x}

x = \frac{- ln ( 2 ) + 5 ln ( 3 )}{2 ( - ln ( 7 ) + 2 ln ( 3 ) )}

Solution steps

2 (3^{4 x - 5}) = 7^{2 x}

Apply exponent rules

ln (2) + (4 x - 5) ln (3) = 2 x ln (7)

Solve

ln (2) + (4 x - 5) ln (3) = 2 x ln (7) : x = \frac{- ln ( 2 ) + 5 ln ( 3 )}{2 ( - ln ( 7 ) + 2 ln ( 3 ) )}

x = \frac{- ln ( 2 ) + 5 ln ( 3 )}{2 ( - ln ( 7 ) + 2 ln ( 3 ) )}

5^{x - 1} = 5^{x} - 5

(\frac{1}{2})^{x} = \frac{1}{32}

2 7^{x} = 9^{x - 2}

3^{x} = 60

4^{x^{2} - 6 x} = 16384
