simplify (-x+20)e^{-4x}

Solution

simplify

(- x + 20) e^{- 4 x}

Solution

\frac{- x + 20}{e ^{4 x}}

Solution steps

(- x + 20) e^{- 4 x}

Apply exponent rule:

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

= \frac{1}{e ^{4 x}} (- x + 20)

Multiply fractions:

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

= \frac{1 \cdot ( - x + 20 )}{e ^{4 x}}

1 \cdot (- x + 20) = - x + 20

= \frac{- x + 20}{e ^{4 x}}
