\frac{1}{e}

Decimal Notation

0.36787 \dots

Solution steps

e^{- 2 \cdot \frac{1}{2}}

Apply exponent rule:

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

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

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

= \frac{1}{e}

1 0^{3.4}

\frac{1}{4} \cdot e^{- x} \cdot (x \cdot cos (x) + (x^{2} + 1) \cdot sin (x))

8.8 \cdot 1 0^{- 18}

\frac{3 ^{2}}{2 !} \cdot e^{- 3}

e^{\frac{- Z r}{a}} \cdot e^{\frac{- Z r}{a}}
