9^{2x-4}=27^{x-1}

9^{2 x - 4} = 2 7^{x - 1}

x = 5

Solution steps

9^{2 x - 4} = 2 7^{x - 1}

Apply exponent rules

2 (2 x - 4) = 3 (x - 1)

Solve

2 (2 x - 4) = 3 (x - 1) : x = 5

x = 5

91500 = 100000 - 272000 (\frac{1}{2})^{x}

- 4.5 e^{- 0.3 x} + 9 e^{- 0.6 x} = 0

5 e^{- 3 x} - 4 = 6

\frac{1}{8 1 ^{(x - 2)}} = 2 7^{(1 - x)}

e^{12 x - 1} = (e^{10})^{x}
