simplify-21.28*e^{-2}

simplify

- 21.28 \cdot e^{- 2}

- 2.87993 \dots

Solution steps

- 21.28 e^{- 2}

Apply exponent rule:

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

= - 21.28 \cdot \frac{1}{e ^{2}}

Multiply fractions:

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

= - \frac{1 \cdot 21.28}{e ^{2}}

Multiply the numbers:

1 \cdot 21.28 = 21.28

= - \frac{21.28}{e ^{2}}

Simplify

\frac{21.28}{e ^{2}} : 2.87993 \dots

= - 2.87993 \dots

6.42 \cdot 1 0^{- 6} \cdot 445.315

10 \cdot 3.33 \cdot 1 0^{- 2}

- 4.3 \cdot 1 0^{- 6} (61038 - 1.44 \cdot 1 0^{5})

0.28 \cdot 1 0^{- 2}
