simplify e^{-x}*x^2

Solution

simplify

e^{- x} \cdot x^{2}

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

Solution steps

e^{- x} x^{2}

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}}

e^{- 2 l n (l n (x))}

e^{- l n (s i n (x) s i n (y))}

e^{- 1090}

(2 x)^{6}

- (1.43 \cdot 1 0^{- 8}) \frac{- 3 - 3}{7.83 \cdot 1 0 ^{- 3}}
