Question

How do you simplify `((3.2x 10^4) x ( 4.9 x 10^-4)) / (2.8 x 10^-7)`?

Answer 1

Group the coefficients and the exponents and process them separately:

`((3.2xx10^4)xx(4.9xx10^(-4)))/(2.8xx10^(-7))`

`= (3.2xx4.9)/(2.8) xx (10^4xx10^(-4))/(10^(-7))`

`=5.6 xx (10^0)/(10^(-7))`

`= 5.6 xx 10^7`
