Group the coefficients and the exponents and process them separately:

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

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

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

$= 5.6 xx 10^7$

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