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

Solution

simplify

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

Solution

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

Solution steps

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

Apply exponent rule:

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

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

Multiply fractions:

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

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

Multiply:

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

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