simplify (a+b)*e^{-st}

Solution

simplify

(a + b) \cdot e^{- s t}

Solution

\frac{a + b}{e ^{s t}}

Solution steps

(a + b) e^{- s t}

Apply exponent rule:

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

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

Multiply fractions:

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

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

1 \cdot (a + b) = a + b

= \frac{a + b}{e ^{s t}}
