simplify 125.5*10^{-12}

Solution

simplify

125.5 \cdot 1 0^{- 12}

Solution

\frac{251}{2000000000000}

+1

Decimal Notation

1.255 E - 10

Solution steps

125.5 \cdot 1 0^{- 12}

Apply exponent rule:

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

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

= 125.5 \cdot \frac{1}{1 0 ^{12}}

125.5 \cdot \frac{1}{1 0 ^{12}} = \frac{125.5}{1 0 ^{12}}

= \frac{125.5}{1 0 ^{12}}

\frac{125.5}{1 0 ^{12}} = \frac{1255}{10 \cdot 1 0 ^{12}}

= \frac{1255}{10 \cdot 1 0 ^{12}}

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

= \frac{1255}{1 0 ^{13}}

Factor the number:

1255 = 5 \cdot 251

= \frac{5 \cdot 251}{1 0 ^{13}}

Factor

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

= \frac{5 \cdot 251}{5 ^{13} \cdot 2 ^{13}}

\frac{5}{5 ^{13}} = \frac{1}{5 ^{12}}

= \frac{251}{5 ^{12} \cdot 2 ^{13}}

5^{12} \cdot 2^{13} = 2000000000000

= \frac{251}{2000000000000}
