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

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

x = - 1

Solution steps

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

Apply exponent rules

- x - 3 = - 2

Solve

- x - 3 = - 2 : x = - 1

x = - 1

3^{x + 1} - 10 (3^{x}) = - 3

\frac{3}{2} = 1^{x}

5^{x + 3} = (\frac{( 1 )}{( 125 )})^{x}

e^{x} \cdot e^{- x} = 1

3^{x} + 3^{- x + 3} = 12
