Solution steps

2.8 e^{- 5 (0.45)}

Apply exponent rule:

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

= 2.8 \cdot \frac{1}{e ^{5 \cdot 0.45}}

Multiply the numbers:

5 \cdot 0.45 = 2.25

= 2.8 \cdot \frac{1}{e ^{2.25}}

Multiply fractions:

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

= \frac{1 \cdot 2.8}{e ^{2.25}}

Multiply the numbers:

1 \cdot 2.8 = 2.8

= \frac{2.8}{e ^{2.25}}

e^{2.25} = 9.48773 \dots

= \frac{2.8}{9.48773 \dots}

Divide the numbers:

\frac{2.8}{9.48773 \dots} = 0.29511 \dots

= 0.29511 \dots
