simplify (2.810^{-3})(-2)

Solution

simplify

(2.8 \cdot 1 0^{- 3}) \cdot (- 2)

Solution

- 0.0056

Solution steps

(2.8 \cdot 1 0^{- 3}) (- 2)

Apply rule:

a (- b) = - ab

(2.8 \cdot 1 0^{- 3}) (- 2) = - 2.8 \cdot 1 0^{- 3} \cdot 2

= - 2.8 \cdot 1 0^{- 3} \cdot 2

Multiply the numbers:

- 2.8 \cdot 2 = - 5.6

= - 5.6 \cdot 1 0^{- 3}

= - 1 0^{- 3} \cdot 5.6

Apply exponent rule:

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

1 0^{- 3} = \frac{1}{1 0 ^{3}}

= - \frac{1}{1 0 ^{3}} \cdot 5.6

1 0^{3} = 1000

= - \frac{1}{1000} \cdot 5.6

- \frac{1}{1000} \cdot 5.6 = - \frac{5.6}{1000}

= - \frac{5.6}{1000}

Divide the numbers:

\frac{5.6}{1000} = 0.0056

= - 0.0056
