simplify 4.2*10^{-2}

Solution

simplify

4.2 \cdot 1 0^{- 2}

Solution

0.042

Solution steps

4.2 \cdot 1 0^{- 2}

Apply exponent rule:

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

1 0^{- 2} = \frac{1}{1 0 ^{2}}

= 4.2 \cdot \frac{1}{1 0 ^{2}}

1 0^{2} = 100

= 4.2 \cdot \frac{1}{100}

4.2 \cdot \frac{1}{100} = \frac{4.2}{100}

= \frac{4.2}{100}

Divide the numbers:

\frac{4.2}{100} = 0.042

= 0.042
