simplify n^2e^{-n}

Solution

simplify

n^{2} e^{- n}

\frac{n ^{2}}{e ^{n}}

Solution steps

n^{2} e^{- n}

Apply exponent rule:

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

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

Multiply fractions:

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

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

Multiply:

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

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

f (j) = e^{(- j \cdot 2 π)}

n + 1 n

e^{- (0.326) \cdot 3}

\frac{d}{d x} ((- 2)^{x} (- 2)^{x})

f (x) = e^{- \frac{4.7059}{x} \cdot π}
