simplify

\frac{1}{2} \cdot e^{- 0.25}

0.38940 \dots

Solution steps

\frac{1}{2} e^{- 0.25}

Apply exponent rule:

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

= \frac{1}{2} \cdot \frac{1}{e ^{0.25}}

Multiply fractions:

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

= \frac{1 \cdot 1}{2 e ^{0.25}}

Multiply the numbers:

1 \cdot 1 = 1

= \frac{1}{2 e ^{0.25}}

e^{0.25} = 1.28402 \dots

= \frac{1}{2 \cdot 1.28402 \dots}

Multiply the numbers:

2 \cdot 1.28402 \dots = 2.56805 \dots

= \frac{1}{2.56805 \dots}

Divide the numbers:

\frac{1}{2.56805 \dots} = 0.38940 \dots

= 0.38940 \dots
