simplify e^{-x}*2

Solution

simplify

e^{- x} \cdot 2

\frac{2}{e ^{x}}

Solution steps

e^{- x} \cdot 2

Apply exponent rule:

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

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

Multiply fractions:

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

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

Multiply the numbers:

1 \cdot 2 = 2

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

e^{- x} \cdot 3

500 \cdot 1.7 \cdot 1 0^{- 3}

e^{- (\frac{π}{1 - 0. 5 ^{2}})} \cdot 100

50 e^{- x}

(- 2) (200)^{- 3} (0.01)
