simplify-2e^{-2x}\times e^{-x}

simplify

- 2 e^{- 2 x} \cdot e^{- x}

- 2 e^{- 3 x}

Solution steps

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

Apply exponent rule:

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

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

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

Add similar elements:

- 2 x - x = - 3 x

= - 2 e^{- 3 x}

e^{- 0.11 \cdot \frac{60}{365}} \cdot 0.46888

e^{- 0.054}

x e^{- λ x}

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

e^{- 0.086 \cdot 12}
