7^{-x}*7^{-x}=343

7^{- x} \cdot 7^{- x} = 343

x = - \frac{3}{2}

Decimal Notation

x = - 1.5

Solution steps

7^{- x} \cdot 7^{- x} = 343

Apply exponent rules

- 2 x = 3

Solve

- 2 x = 3 : x = - \frac{3}{2}

x = - \frac{3}{2}

0 = 10 e^{0.002 x}

6^{4 x - 4} = 1

e^{x^{2}} = e^{x} (e^{x - 1})^{2}

\frac{1}{2 ^{x}} = 8

2^{2 x} - 3 \cdot 2^{2 x} + 2 = 0
