simplify e^{-3x}*(-e^{-3x})

Solution

simplify

e^{- 3 x} \cdot (- e^{- 3 x})

Solution

- \frac{1}{e ^{6 x}}

Solution steps

e^{- 3 x} (- e^{- 3 x})

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

= \frac{1}{e ^{3 x}} (- e^{- 3 x})

Remove parentheses:

(- a) = - a

= - \frac{1}{e ^{3 x}} e^{- 3 x}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= - \frac{1 \cdot e ^{- 3 x}}{e ^{3 x}}

Multiply:

1 \cdot e^{- 3 x} = e^{- 3 x}

= - \frac{e ^{- 3 x}}{e ^{3 x}}

Apply exponent rule:

\frac{x ^{a}}{x ^{b}} = x^{a - b}

\frac{e ^{- 3 x}}{e ^{3 x}} = e^{- 3 x - 3 x} = e^{- 6 x}

= - \frac{1}{e ^{6 x}}
