Solution

simplify

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

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

Decimal Notation

0.06766 \dots

Solution steps

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

Apply exponent rule:

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

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

Multiply fractions:

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

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

Multiply the numbers:

1 \cdot 1 = 1

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

e^{- x} e^{- y}

\frac{17 + 17}{34}^{2}

2.8 \times 1 0^{- 4}

0.23 \cdot 1 0^{- 3}

(3 x 1 0^{8}) (6.8 x 1 0^{- 13})
