simplify x^2e^{-9x}

Solution

simplify

x^{2} e^{- 9 x}

\frac{x ^{2}}{e ^{9 x}}

Solution steps

x^{2} e^{- 9 x}

Apply exponent rule:

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

= \frac{1}{e ^{9 x}} x^{2}

Multiply fractions:

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

= \frac{1 \cdot x ^{2}}{e ^{9 x}}

Multiply:

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

= \frac{x ^{2}}{e ^{9 x}}

1.68 \times 1 0^{- 8} \frac{554}{0.00019625}

3^{\frac{1}{4}} \times 2 7^{\frac{1}{4}}

- 7 e^{- l n (7)}

2^{\frac{1}{2}} \times 3^{\frac{1}{2}}

e^{3 x} \times e^{- 4 x}
