Solution steps

400 e^{- 0.032 (4)}

Apply exponent rule:

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

= 400 \cdot \frac{1}{e ^{4 \cdot 0.032}}

Multiply the numbers:

0.032 \cdot 4 = 0.128

= 400 \cdot \frac{1}{e ^{0.128}}

Multiply fractions:

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

= \frac{1 \cdot 400}{e ^{0.128}}

Multiply the numbers:

1 \cdot 400 = 400

= \frac{400}{e ^{0.128}}

e^{0.128} = 1.13655 \dots

= \frac{400}{1.13655 \dots}

Divide the numbers:

\frac{400}{1.13655 \dots} = 351.94135 \dots

= 351.94135 \dots
