simplify

(4 - 2 (- 1)) e^{- 2}

\frac{6}{e ^{2}}

Decimal Notation

0.81201 \dots

Solution steps

(4 - 2 (- 1)) e^{- 2}

Apply exponent rule:

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

= \frac{1}{e ^{2}} (4 - 2 (- 1))

Apply rule

- (- a) = a

= (4 + 2 \cdot 1) \frac{1}{e ^{2}}

Multiply the numbers:

2 \cdot 1 = 2

= \frac{1}{e ^{2}} (4 + 2)

Add the numbers:

4 + 2 = 6

= 6 \cdot \frac{1}{e ^{2}}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{1 \cdot 6}{e ^{2}}

Multiply the numbers:

1 \cdot 6 = 6

= \frac{6}{e ^{2}}
