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

Solution

simplify

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

Solution

- \frac{4}{e ^{2 x}}

Solution steps

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

Apply exponent rule:

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

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

Remove parentheses:

(- a) = - a

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

Multiply fractions:

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

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

Multiply the numbers:

1 \cdot 2 \cdot 2 = 4

= - \frac{4}{e ^{2 x}}
