simplify e^{-2}*(2^1)/(1!)

Solution

simplify

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

Solution

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

+1

Decimal Notation

0.27067 \dots

Solution steps

e^{- 2} \frac{2 ^{1}}{1 !}

Apply exponent rule:

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

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

Apply rule

a^{1} = a

2^{1} = 2

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

Multiply fractions:

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

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

Multiply the numbers:

1 \cdot 2 = 2

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

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

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