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

Solution

simplify

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

Solution

\frac{1}{e ^{2 x}}

Solution steps

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

Apply exponent rule:

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

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

Apply rule

- (- a) = a

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

Multiply fractions:

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

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

Multiply:

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

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

Apply exponent rule:

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

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

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