simplify 1.2*10^{-10}

Solution

simplify

1.2 \cdot 1 0^{- 10}

Solution

\frac{3}{25000000000}

+1

Decimal Notation

1.2 E - 10

Solution steps

1.2 \cdot 1 0^{- 10}

Apply exponent rule:

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

1 0^{- 10} = \frac{1}{1 0 ^{10}}

= 1.2 \cdot \frac{1}{1 0 ^{10}}

1.2 \cdot \frac{1}{1 0 ^{10}} = \frac{1.2}{1 0 ^{10}}

= \frac{1.2}{1 0 ^{10}}

\frac{1.2}{1 0 ^{10}} = \frac{12}{10 \cdot 1 0 ^{10}}

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

10 \cdot 1 0^{10} = 1 0^{11}

= \frac{12}{1 0 ^{11}}

Factor

12 : 2^{2} \cdot 3

= \frac{2 ^{2} \cdot 3}{1 0 ^{11}}

Factor

1 0^{11} : 2^{11} \cdot 5^{11}

= \frac{2 ^{2} \cdot 3}{2 ^{11} \cdot 5 ^{11}}

\frac{2 ^{2}}{2 ^{11}} = \frac{1}{2 ^{9}}

= \frac{3}{2 ^{9} \cdot 5 ^{11}}

2^{9} \cdot 5^{11} = 25000000000

= \frac{3}{25000000000}
