simplify e^{-y}(-2x)

Solution

simplify

e^{- y} (- 2 x)

Solution

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

Solution steps

e^{- y} (- 2 x)

Apply exponent rule:

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

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

Remove parentheses:

(- a) = - a

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

Multiply fractions:

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

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

Multiply the numbers:

1 \cdot 2 = 2

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