simplify 2x(e^{-x})

Solution

simplify

2 x (e^{- x})

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

Solution steps

2 x (e^{- x})

Apply exponent rule:

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

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

Multiply fractions:

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

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

Multiply the numbers:

1 \cdot 2 = 2

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

(6.6726 \cdot 1 0^{- 11}) (3.17 \cdot 1 0^{7})

\frac{( x ^{2} + 1 ) ^{4}}{x ^{4}}

1.57 \cdot 1 0^{- 3} (1 + 5)

e^{- \frac{5}{3.1}}

e^{- 0.15 (5)}
