simplify xe^{-x}dx

Solution

simplify

x e^{- x} d x

Solution

\frac{x d x}{e ^{x}}

Solution steps

x e^{- x} d x

Apply exponent rule:

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

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

Multiply fractions:

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

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

Multiply:

1 \cdot x = x

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