simplify 4.2*10^{-3}

Solution

simplify

4.2 \cdot 1 0^{- 3}

Solution

0.0042

Solution steps

4.2 \cdot 1 0^{- 3}

Apply exponent rule:

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

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

= 4.2 \cdot \frac{1}{1 0 ^{3}}

1 0^{3} = 1000

= 4.2 \cdot \frac{1}{1000}

4.2 \cdot \frac{1}{1000} = \frac{4.2}{1000}

= \frac{4.2}{1000}

Divide the numbers:

\frac{4.2}{1000} = 0.0042

= 0.0042
