simplify-e^{-x}(e^{-2x})

simplify

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

- e^{- 3 x}

Solution steps

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

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

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

= - e^{- x - 2 x}

Add similar elements:

- x - 2 x = - 3 x

= - e^{- 3 x}

\frac{- 18}{2}

6.1 \cdot 1 0^{- 3}

4 e^{- \frac{( 3 )}{3}}

(3 x^{2} y) (2 x z^{2}) (4 y^{2} z)

\frac{2}{13}
