simplify 2.1e^{-2.1}

Solution

simplify

2.1 e^{- 2.1}

Solution

0.25715 \dots

Solution steps

2.1 e^{- 2.1}

Apply exponent rule:

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

= 2.1 \cdot \frac{1}{e ^{2.1}}

Multiply fractions:

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

= \frac{1 \cdot 2.1}{e ^{2.1}}

Multiply the numbers:

1 \cdot 2.1 = 2.1

= \frac{2.1}{e ^{2.1}}

e^{2.1} = 8.16616 \dots

= \frac{2.1}{8.16616 \dots}

Divide the numbers:

\frac{2.1}{8.16616 \dots} = 0.25715 \dots

= 0.25715 \dots
