simplify 1.9e^{-1.9}

Solution

simplify

1.9 e^{- 1.9}

Solution

0.28418 \dots

Solution steps

1.9 e^{- 1.9}

Apply exponent rule:

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

= 1.9 \cdot \frac{1}{e ^{1.9}}

Multiply fractions:

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

= \frac{1 \cdot 1.9}{e ^{1.9}}

Multiply the numbers:

1 \cdot 1.9 = 1.9

= \frac{1.9}{e ^{1.9}}

e^{1.9} = 6.68589 \dots

= \frac{1.9}{6.68589 \dots}

Divide the numbers:

\frac{1.9}{6.68589 \dots} = 0.28418 \dots

= 0.28418 \dots
