simplify 21.9*10^{-2}

Solution

simplify

21.9 \cdot 1 0^{- 2}

Solution

0.219

Solution steps

21.9 \cdot 1 0^{- 2}

Apply exponent rule:

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

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

= 21.9 \cdot \frac{1}{1 0 ^{2}}

1 0^{2} = 100

= 21.9 \cdot \frac{1}{100}

21.9 \cdot \frac{1}{100} = \frac{21.9}{100}

= \frac{21.9}{100}

Divide the numbers:

\frac{21.9}{100} = 0.219

= 0.219
