simplify (4^1)/(1!)*e^{-1}

Solution

simplify

\frac{4 ^{1}}{1 !} \cdot e^{- 1}

Solution

\frac{4}{e}

+1

Decimal Notation

1.47151 \dots

Solution steps

\frac{4 ^{1}}{1 !} e^{- 1}

Apply exponent rule:

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

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

Apply rule

a^{1} = a

4^{1} = 4

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

Multiply fractions:

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

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

Multiply the numbers:

4 \cdot 1 = 4

= \frac{4}{e 1 !}

1! e = e

= \frac{4}{e}
