simplify

68.28 \cdot e^{- 0.1155 \cdot 2}

54.19653 \dots

Solution steps

68.28 e^{- 0.1155 \cdot 2}

Apply exponent rule:

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

= 68.28 \cdot \frac{1}{e ^{2 \cdot 0.1155}}

Multiply the numbers:

0.1155 \cdot 2 = 0.231

= 68.28 \cdot \frac{1}{e ^{0.231}}

Multiply fractions:

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

= \frac{1 \cdot 68.28}{e ^{0.231}}

Multiply the numbers:

1 \cdot 68.28 = 68.28

= \frac{68.28}{e ^{0.231}}

e^{0.231} = 1.25985 \dots

= \frac{68.28}{1.25985 \dots}

Divide the numbers:

\frac{68.28}{1.25985 \dots} = 54.19653 \dots

= 54.19653 \dots
