simplify 4.2*10^{-8}

Solution

simplify

4.2 \cdot 1 0^{- 8}

Solution

0.000000042

Solution steps

4.2 \cdot 1 0^{- 8}

Apply exponent rule:

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

1 0^{- 8} = \frac{1}{1 0 ^{8}}

= 4.2 \cdot \frac{1}{1 0 ^{8}}

1 0^{8} = 100000000

= 4.2 \cdot \frac{1}{100000000}

4.2 \cdot \frac{1}{100000000} = \frac{4.2}{100000000}

= \frac{4.2}{100000000}

Divide the numbers:

\frac{4.2}{100000000} = 0.000000042

= 0.000000042
