simplify 4xe^{-x}

Solution

simplify

4 x e^{- x}

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

Solution steps

4 x e^{- x}

Apply exponent rule:

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

= 4 \cdot \frac{1}{e ^{x}} x

Multiply fractions:

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

= \frac{1 \cdot 4 x}{e ^{x}}

Multiply the numbers:

1 \cdot 4 = 4

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

4 (6 x^{10} y^{5} z) (10 x^{3} y^{4} z^{2})

4.5 \cdot 1 0^{- 7}

12 e^{- 12 (1)}

523961.66 (1 + \frac{0.12}{12})^{- 24}

8.85 \cdot 1 0^{- 12} (5) (\frac{1}{6 \cdot 1 0 ^{7}} - \frac{1}{1 0 ^{7}})
