simplify e^{-(-x)}

Solution

simplify

e^{- (- x)}

Solution

e^{x}

Solution steps

e^{- (- x)}

Apply exponent rule:

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

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

Remove parentheses:

(- a) = - a

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

Apply exponent rule:

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

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

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

Apply the fraction rule:

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

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

Apply the fraction rule:

\frac{a}{1} = a

= e^{x}
