simplify 72.5*10^{-12}

Solution

simplify

72.5 \cdot 1 0^{- 12}

Solution

\frac{29}{400000000000}

+1

Decimal Notation

7.25 E - 11

Solution steps

72.5 \cdot 1 0^{- 12}

Apply exponent rule:

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

1 0^{- 12} = \frac{1}{1 0 ^{12}}

= 72.5 \cdot \frac{1}{1 0 ^{12}}

72.5 \cdot \frac{1}{1 0 ^{12}} = \frac{72.5}{1 0 ^{12}}

= \frac{72.5}{1 0 ^{12}}

\frac{72.5}{1 0 ^{12}} = \frac{725}{10 \cdot 1 0 ^{12}}

= \frac{725}{10 \cdot 1 0 ^{12}}

10 \cdot 1 0^{12} = 1 0^{13}

= \frac{725}{1 0 ^{13}}

Factor

725 : 5^{2} \cdot 29

= \frac{5 ^{2} \cdot 29}{1 0 ^{13}}

Factor

1 0^{13} : 5^{13} \cdot 2^{13}

= \frac{5 ^{2} \cdot 29}{5 ^{13} \cdot 2 ^{13}}

\frac{5 ^{2}}{5 ^{13}} = \frac{1}{5 ^{11}}

= \frac{29}{5 ^{11} \cdot 2 ^{13}}

5^{11} \cdot 2^{13} = 400000000000

= \frac{29}{400000000000}
