simplify 2e^{-2/2}

Solution

simplify

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

Solution

\frac{2}{e}

+1

Decimal Notation

0.73575 \dots

Solution steps

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

Apply exponent rule:

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

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

Apply rule

\frac{a}{a} = 1

\frac{2}{2} = 1

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

Apply rule

a^{1} = a

e^{1} = e

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

Multiply fractions:

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

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

Multiply the numbers:

1 \cdot 2 = 2

= \frac{2}{e}
