simplify (-2)e^{-3}

Solution

simplify

(- 2) e^{- 3}

- \frac{2}{e ^{3}}

Decimal Notation

- 0.09957 \dots

Solution steps

(- 2) e^{- 3}

Apply exponent rule:

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

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

Remove parentheses:

(- a) = - a

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

Multiply fractions:

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

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

Multiply the numbers:

1 \cdot 2 = 2

= - \frac{2}{e ^{3}}

(6.7 \cdot 1 0^{8}) (3.3 \cdot 1 0^{6})

e^{- 2 t} (- \frac{2}{15} e^{2 t})

0.04 (2000) \cdot (1 + 0.0001 (2000))^{- \frac{1}{2}}

(2 π x) (x (x - 1)^{2})

1.334 \cdot 1 0^{- 9} (\frac{0.3}{0 , 5})
