simplify 4.2*10^{-7}

Solution

simplify

4.2 \cdot 1 0^{- 7}

Solution

0.00000042

Solution steps

4.2 \cdot 1 0^{- 7}

Apply exponent rule:

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

1 0^{- 7} = \frac{1}{1 0 ^{7}}

= 4.2 \cdot \frac{1}{1 0 ^{7}}

1 0^{7} = 10000000

= 4.2 \cdot \frac{1}{10000000}

4.2 \cdot \frac{1}{10000000} = \frac{4.2}{10000000}

= \frac{4.2}{10000000}

Divide the numbers:

\frac{4.2}{10000000} = 0.00000042

= 0.00000042
