simplify (1+e^x)*e^{-x}

Solution

simplify

(1 + e^{x}) \cdot e^{- x}

Solution

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

Solution steps

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

Apply exponent rule:

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

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

Multiply fractions:

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

= \frac{1 \cdot ( 1 + e ^{x} )}{e ^{x}}

1 \cdot (1 + e^{x}) = 1 + e^{x}

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