simplify (n-3)e^{-n}

Solution

simplify

(n - 3) e^{- n}

Solution

\frac{n - 3}{e ^{n}}

Solution steps

(n - 3) e^{- n}

Apply exponent rule:

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

= \frac{1}{e ^{n}} (n - 3)

Multiply fractions:

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

= \frac{1 \cdot ( n - 3 )}{e ^{n}}

1 \cdot (n - 3) = n - 3

= \frac{n - 3}{e ^{n}}
