Solution steps

25 e^{- 0.15 (3)}

Apply exponent rule:

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

= 25 \cdot \frac{1}{e ^{3 \cdot 0.15}}

Multiply the numbers:

0.15 \cdot 3 = 0.45

= 25 \cdot \frac{1}{e ^{0.45}}

Multiply fractions:

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

= \frac{1 \cdot 25}{e ^{0.45}}

Multiply the numbers:

1 \cdot 25 = 25

= \frac{25}{e ^{0.45}}

e^{0.45} = 1.56831 \dots

= \frac{25}{1.56831 \dots}

Divide the numbers:

\frac{25}{1.56831 \dots} = 15.94070 \dots

= 15.94070 \dots
