simplify-e^{-x}*e^{-2x}

simplify

- e^{- x} \cdot 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}

1.5 \cdot 1 0^{- 6}

\frac{e ^{- t}}{e ^{t}}
