7776^{x-1}=216^{2x-4}

777 6^{x - 1} = 21 6^{2 x - 4}

x = 7

Solution steps

777 6^{x - 1} = 21 6^{2 x - 4}

Apply exponent rules

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

Solve

5 (x - 1) = 3 (2 x - 4) : x = 7

x = 7

2^{x - 1} = \frac{17}{2}

4 (3 e^{- x} x^{2} - e^{- x} x^{3}) = 0

8 1^{x - 2} = 2 7^{2 x}

3 e^{3 x} - e^{- x} = 0

2^{x + 1} = 1
