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

Solution

expand

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

Solution

e^{x} + 1

Solution steps

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

Apply the distributive law:

a (b + c) = ab + a c

a = e^{x}, b = 1, c = e^{- x}

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

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

Simplify

1 \cdot e^{x} + e^{x} e^{- x} : e^{x} + 1

= e^{x} + 1
