27^{3x-3}=81^{2x+4}

2 7^{3 x - 3} = 8 1^{2 x + 4}

x = 25

Solution steps

2 7^{3 x - 3} = 8 1^{2 x + 4}

Apply exponent rules

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

Solve

3 (3 x - 3) = 4 (2 x + 4) : x = 25

x = 25

x^{x} = 16

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

5^{1 - x} = 2^{x}

3 6^{3} = 6^{x - 1}

x, \frac{J}{e} = J e^{- x y}
