simplify 15e^{-2.5}

Solution

simplify

15 e^{- 2.5}

Solution

1.23127 \dots

Solution steps

15 e^{- 2.5}

Apply exponent rule:

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

= 15 \cdot \frac{1}{e ^{2.5}}

Multiply fractions:

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

= \frac{1 \cdot 15}{e ^{2.5}}

Multiply the numbers:

1 \cdot 15 = 15

= \frac{15}{e ^{2.5}}

e^{2.5} = 12.18249 \dots

= \frac{15}{12.18249 \dots}

Divide the numbers:

\frac{15}{12.18249 \dots} = 1.23127 \dots

= 1.23127 \dots
