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

Solution

simplify

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

Solution

- 2 e

+1

Decimal Notation

- 5.43656 \dots

Solution steps

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

Apply exponent rule:

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

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

Remove parentheses:

(- a) = - a

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

(- 1)^{3} = - 1

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

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

= 2 (- 1) e

Remove parentheses:

(- a) = - a

= - 2 \cdot 1 e

Multiply the numbers:

2 \cdot 1 = 2

= - 2 e
