UNCERTAINTY IN MEASUREMENT -

Multiplication and Division

For multiplying or dividing two numbers

(4.5 X 104) X (2.5 X 105) =  (4.5 X 2.5)X (104+5) = 11.25 X 109 = 1.125 X 1010 

(4.5 X 104 ) / (2.5 X 105) = (4.5 / 2.5) X 104-5 = 1.8 X 10-1

 

5.6\frac{g}{cm^{3}}= \frac{5.6\times 10^{-3}kg}{10^{-6}m^{3}}= 5600\frac{kg}{m^{3}}
