simplify e^{-(-0.2)}

Solution

simplify

e^{- (- 0.2)}

Solution

1.22140 \dots

Solution steps

e^{- (- 0.2)}

Apply exponent rule:

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

= \frac{1}{e ^{(- 0.2)}}

Remove parentheses:

(- a) = - a

= \frac{1}{e ^{- 0.2}}

Apply exponent rule:

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

e^{- 0.2} = \frac{1}{e ^{0.2}}

= \frac{1}{\frac{1}{e ^{0.2}}}

Apply the fraction rule:

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

= \frac{e ^{0.2}}{1}

Apply the fraction rule:

\frac{a}{1} = a

= e^{0.2}

e^{0.2} = 1.22140 \dots

= 1.22140 \dots
