simplify e^{-2}(2^2)/(2!)

Solution

simplify

e^{- 2} \frac{2 ^{2}}{2 !}

Solution

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

+1

Solution steps

e^{- 2} \frac{2 ^{2}}{2 !}

Apply exponent rule:

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

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

Multiply fractions:

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

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

Multiply:

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

= \frac{2 ^{2}}{e ^{2} \cdot 2 !}

2^{2} = 4

= \frac{4}{e ^{2} \cdot 2 !}

e^{2} \cdot 2! = 2 e^{2}

= \frac{4}{2 e ^{2}}

Divide the numbers:

\frac{4}{2} = 2

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