simplify 7.5*10^{-10}

Solution

simplify

7.5 \cdot 1 0^{- 10}

Solution

\frac{3}{4000000000}

+1

Decimal Notation

7.5 E - 10

Solution steps

7.5 \cdot 1 0^{- 10}

Apply exponent rule:

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

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

= 7.5 \cdot \frac{1}{1 0 ^{10}}

7.5 \cdot \frac{1}{1 0 ^{10}} = \frac{7.5}{1 0 ^{10}}

= \frac{7.5}{1 0 ^{10}}

\frac{7.5}{1 0 ^{10}} = \frac{75}{10 \cdot 1 0 ^{10}}

= \frac{75}{10 \cdot 1 0 ^{10}}

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

= \frac{75}{1 0 ^{11}}

Factor

75 : 5^{2} \cdot 3

= \frac{5 ^{2} \cdot 3}{1 0 ^{11}}

Factor

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

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

\frac{5 ^{2}}{5 ^{11}} = \frac{1}{5 ^{9}}

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

5^{9} \cdot 2^{11} = 4000000000

= \frac{3}{4000000000}
