Question

How do you divide `(3.5 X 10^2) /(2.5 X 10^-3)`?

Answer 1

Separate and do the division of the coefficients and the exponents individually before re-combining

`(3.5xx10^2)/(2.5xx10^(-3)) = (3.5)/(2.5) xx 10^2/10^(-3)`

`(3.5)/(2.5) = 1.4`

`10^2/10^(-3) = 10^2xx10^3 = 10^5`

So
`(3.5xx10^2)/(2.5xx10^(-3)) = 1.4 xx 10^5`
