simplify x^5e^{-x}

Solution

simplify

x^{5} e^{- x}

\frac{x ^{5}}{e ^{x}}

Solution steps

x^{5} e^{- x}

Apply exponent rule:

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

= \frac{1}{e ^{x}} x^{5}

Multiply fractions:

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

= \frac{1 \cdot x ^{5}}{e ^{x}}

Multiply:

1 \cdot x^{5} = x^{5}

= \frac{x ^{5}}{e ^{x}}

(1.673 \cdot 1 0^{- 27}) (8.5 \cdot 1 0^{7})

2.6 \cdot e^{- 2.5}

(4 x^{5} y^{4}) \cdot (5 x^{5} y^{4})

(x^{2} + 1) (2 x) x

4.6 \cdot 1 0^{- 7} \frac{( 299792458 )}{2 4}
