simplify 4.2*10^{-9}

Solution

simplify

4.2 \cdot 1 0^{- 9}

Solution

0.0000000042

Solution steps

4.2 \cdot 1 0^{- 9}

Apply exponent rule:

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

1 0^{- 9} = \frac{1}{1 0 ^{9}}

= 4.2 \cdot \frac{1}{1 0 ^{9}}

1 0^{9} = 1000000000

= 4.2 \cdot \frac{1}{1000000000}

4.2 \cdot \frac{1}{1000000000} = \frac{4.2}{1000000000}

= \frac{4.2}{1000000000}

Divide the numbers:

\frac{4.2}{1000000000} = 0.0000000042

= 0.0000000042
