simplify e^{-2}(-2)

Solution

simplify

e^{- 2} (- 2)

- \frac{2}{e ^{2}}

Decimal Notation

- 0.27067 \dots

Solution steps

e^{- 2} (- 2)

Apply exponent rule:

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

= (- 2) \frac{1}{e ^{2}}

Remove parentheses:

(- a) = - a

= - \frac{1}{e ^{2}} \cdot 2

Multiply fractions:

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

= - \frac{1 \cdot 2}{e ^{2}}

Multiply the numbers:

1 \cdot 2 = 2

= - \frac{2}{e ^{2}}
