simplify (e^{1-1}+e^{2-1}+e^{3-1})^{-1}

simplify

(e^{1 - 1} + e^{2 - 1} + e^{3 - 1})^{- 1}

\frac{1}{e ^{2} + e + 1}

Solution steps

(e^{1 - 1} + e^{2 - 1} + e^{3 - 1})^{- 1}

Apply exponent rule:

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

= \frac{1}{( e ^{1 - 1} + e ^{2 - 1} + e ^{3 - 1} )}

e^{1 - 1} + e^{2 - 1} + e^{3 - 1} = 1 + e + e^{2}

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