Solution steps

e^{- (0 + (- 1))}

Apply exponent rule:

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

= \frac{1}{e ^{(0 - 1)}}

Remove parentheses:

(a) = a

= \frac{1}{e ^{0 - 1}}

Subtract the numbers:

0 - 1 = - 1

= \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
