simplify 20e^{-2x}

Solution

simplify

20 e^{- 2 x}

\frac{20}{e ^{2 x}}

Solution steps

20 e^{- 2 x}

Apply exponent rule:

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

= 20 \cdot \frac{1}{e ^{2 x}}

Multiply fractions:

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

= \frac{1 \cdot 20}{e ^{2 x}}

Multiply the numbers:

1 \cdot 20 = 20

= \frac{20}{e ^{2 x}}

(3 + 2 x)^{- 3}

(5.7 e^{- 5}) (4.56 e^{5})

0.005 (1 0^{- 15})

e^{- 2 t} \cdot u (t)

0.474 \cdot 1 0^{- 3} \cdot 210
