simplify e^{-3}*3

Solution

simplify

e^{- 3} \cdot 3

\frac{3}{e ^{3}}

Decimal Notation

0.14936 \dots

Solution steps

e^{- 3} \cdot 3

Apply exponent rule:

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

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

Multiply fractions:

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

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

Multiply the numbers:

1 \cdot 3 = 3

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

1 3^{- 675}

(x - 1)^{10}

(1 - 2 x)^{- \frac{1}{2}}

0.5 \cdot e^{- 1.83 \cdot 0.8}

\frac{e ^{y}}{e ^{2 y}}
