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

Solution

simplify

2^{2} (e^{- \frac{2}{2}})

Solution

\frac{4}{e}

+1

Decimal Notation

1.47151 \dots

Solution steps

2^{2} (e^{- \frac{2}{2}})

Apply exponent rule:

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

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

Apply rule

\frac{a}{a} = 1

\frac{2}{2} = 1

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

Apply rule

a^{1} = a

e^{1} = e

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

Multiply fractions:

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

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

Multiply:

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

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

2^{2} = 4

= \frac{4}{e}
