simplify 4xe^{-x^2}

Solution

simplify

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

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

Solution steps

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

Apply exponent rule:

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

= 4 \cdot \frac{1}{e ^{x^{2}}} x

Multiply fractions:

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

= \frac{1 \cdot 4 x}{e ^{x^{2}}}

Multiply the numbers:

1 \cdot 4 = 4

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

(1.94 \cdot 1 0^{16})

\frac{a + b}{a - b}

(\frac{9}{8})^{2^{^{'}}}

K (K - 1)^{2} (K - 2)^{2}

(\frac{1}{4}) e^{(- \frac{1}{4} (5))}
