simplify 1.9*e^{-0.4}

Solution

simplify

1.9 \cdot e^{- 0.4}

Solution

1.27360 \dots

Solution steps

1.9 e^{- 0.4}

Apply exponent rule:

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

= 1.9 \cdot \frac{1}{e ^{0.4}}

Multiply fractions:

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

= \frac{1 \cdot 1.9}{e ^{0.4}}

Multiply the numbers:

1 \cdot 1.9 = 1.9

= \frac{1.9}{e ^{0.4}}

e^{0.4} = 1.49182 \dots

= \frac{1.9}{1.49182 \dots}

Divide the numbers:

\frac{1.9}{1.49182 \dots} = 1.27360 \dots

= 1.27360 \dots
