simplify x^2e^{-x}

Solution

simplify

x^{2} e^{- x}

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

Solution steps

x^{2} e^{- x}

Apply exponent rule:

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

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

Multiply fractions:

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

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

Multiply:

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

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

2.2 \cdot e^{- 16}

- 2 (5.96 \cdot 1 0^{- 6}) (0.894)

1 \cdot ((7)^{- 0.345}) \cdot 0.393

\frac{x}{y} \frac{y}{x}

f (t) = e^{- 0.05 t}
