simplify e^{-4}*4

Solution

simplify

e^{- 4} \cdot 4

\frac{4}{e ^{4}}

Decimal Notation

0.07326 \dots

Solution steps

e^{- 4} \cdot 4

Apply exponent rule:

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

= 4 \cdot \frac{1}{e ^{4}}

Multiply fractions:

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

= \frac{1 \cdot 4}{e ^{4}}

Multiply the numbers:

1 \cdot 4 = 4

= \frac{4}{e ^{4}}

f (x) = \frac{e ^{2 x}}{e ^{- x}}

(2 x y^{2}) (4 x^{2} y)

(\frac{1}{2})^{4}

e^{- s t} \cdot e^{t + 7}
