Solution

simplify

e^{- (- 1)}

Solution

e

+1

Decimal Notation

2.71828 \dots

Solution steps

e^{- (- 1)}

Apply exponent rule:

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

= \frac{1}{e ^{(- 1)}}

Remove parentheses:

(- a) = - a

= \frac{1}{e ^{- 1}}

Apply exponent rule:

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

e^{- 1} = \frac{1}{e}

= \frac{1}{\frac{1}{e}}

Apply the fraction rule:

\frac{1}{\frac{b}{c}} = \frac{c}{b}

= \frac{e}{1}

Apply the fraction rule:

\frac{a}{1} = a

= e
