simplify (1+t)e^{-t}

Solution

simplify

(1 + t) e^{- t}

Solution

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

Solution steps

(1 + t) e^{- t}

Apply exponent rule:

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

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

Multiply fractions:

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

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

1 \cdot (1 + t) = 1 + t

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