Question 205182

{{{(9*10^-4)/(3*10^-6))}}}

Let's divide the integers first: {{{9/3=3}}}

Let's then divide the second parts: {{{10^-4/10^-6}}} = {{{10^(-4--6)}}} = 

{{{10^(-4+6)}}}  =  {{{10^2}}}

We now have our answer as: {{{highlight_green(3.0*10^2)}}}


Check:

{{{9*10^-4}}} = 0.0009

{{{3*10^-6}}}  = 0.000003

Original problem: {{{(9*10^-4)/(3*10^-6))}}} = {{{.0009/.000003}}} = 300

Answer: {{{3.0*10^2)}}}  =  300
