simplify 20*e^{-0.8(0.7)}

simplify

20 \cdot e^{- 0.8 (0.7)}

11.42418 \dots

Solution steps

20 e^{- 0.8 (0.7)}

Apply exponent rule:

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

= 20 \cdot \frac{1}{e ^{0.8 \cdot 0.7}}

Multiply the numbers:

0.8 \cdot 0.7 = 0.56

= 20 \cdot \frac{1}{e ^{0.56}}

Multiply fractions:

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

= \frac{1 \cdot 20}{e ^{0.56}}

Multiply the numbers:

1 \cdot 20 = 20

= \frac{20}{e ^{0.56}}

e^{0.56} = 1.75067 \dots

= \frac{20}{1.75067 \dots}

Divide the numbers:

\frac{20}{1.75067 \dots} = 11.42418 \dots

= 11.42418 \dots
