128^x=4\times 2^x

12 8^{x} = 4 \cdot 2^{x}

x = \frac{1}{3}

Decimal Notation

x = 0.33333 \dots

Solution steps

12 8^{x} = 4 \cdot 2^{x}

Apply exponent rules

7 x = x + 2

Solve

7 x = x + 2 : x = \frac{1}{3}

x = \frac{1}{3}

3 x^{2} e^{- x} - x^{3} e^{- x} = 0

7^{x + 1} = 1

7^{x - 2} = 3^{2 - x}

3^{x + 5} = 4

3^{x + 2} - 3^{x} = 216
