simplify 2e^{-2x}dx

Solution

simplify

2 e^{- 2 x} d x

\frac{2 d x}{e ^{2 x}}

Solution steps

2 e^{- 2 x} d x

Apply exponent rule:

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

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

Multiply fractions:

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

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

Multiply the numbers:

1 \cdot 2 = 2

= \frac{2 d x}{e ^{2 x}}

(2 x 1 0^{7}) (3.4 x 1 0^{8})

1.49 \cdot 1 0^{- 3}
