Solution steps

1668 e^{- 0.22 (20)}

Apply exponent rule:

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

= 1668 \cdot \frac{1}{e ^{20 \cdot 0.22}}

Multiply the numbers:

0.22 \cdot 20 = 4.4

= 1668 \cdot \frac{1}{e ^{4.4}}

Multiply fractions:

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

= \frac{1 \cdot 1668}{e ^{4.4}}

Multiply the numbers:

1 \cdot 1668 = 1668

= \frac{1668}{e ^{4.4}}

e^{4.4} = 81.45086 \dots

= \frac{1668}{81.45086 \dots}
