Solution steps

13.271 e^{- 0.054 \cdot 20}

Apply exponent rule:

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

= 13.271 \cdot \frac{1}{e ^{20 \cdot 0.054}}

Multiply the numbers:

0.054 \cdot 20 = 1.08

= 13.271 \cdot \frac{1}{e ^{1.08}}

Multiply fractions:

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

= \frac{1 \cdot 13.271}{e ^{1.08}}

Multiply the numbers:

1 \cdot 13.271 = 13.271

= \frac{13.271}{e ^{1.08}}

e^{1.08} = 2.94467 \dots

= \frac{13.271}{2.94467 \dots}

Divide the numbers:

\frac{13.271}{2.94467 \dots} = 4.50677 \dots

= 4.50677 \dots
