simplify 4.2*10^{-4}

Solution

simplify

4.2 \cdot 1 0^{- 4}

Solution

0.00042

Solution steps

4.2 \cdot 1 0^{- 4}

Apply exponent rule:

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

1 0^{- 4} = \frac{1}{1 0 ^{4}}

= 4.2 \cdot \frac{1}{1 0 ^{4}}

1 0^{4} = 10000

= 4.2 \cdot \frac{1}{10000}

4.2 \cdot \frac{1}{10000} = \frac{4.2}{10000}

= \frac{4.2}{10000}

Divide the numbers:

\frac{4.2}{10000} = 0.00042

= 0.00042
