Solution

simplify

5 e^{- 0.3}

3.70409 \dots

Solution steps

5 e^{- 0.3}

Apply exponent rule:

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

= 5 \cdot \frac{1}{e ^{0.3}}

Multiply fractions:

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

= \frac{1 \cdot 5}{e ^{0.3}}

Multiply the numbers:

1 \cdot 5 = 5

= \frac{5}{e ^{0.3}}

e^{0.3} = 1.34985 \dots

= \frac{5}{1.34985 \dots}

Divide the numbers:

\frac{5}{1.34985 \dots} = 3.70409 \dots

= 3.70409 \dots

3.3 e^{- 5}

164.98538 \cdot 1 0^{- 7}

3.3 e^{- 1}
