How do you simplify #(2.135times10^5)/(3.5times10^12)#?
One way to go about this is to write the whole thing out, answer it, then simplify it:
#2.135 xx 10^5 = 213500#
#3.5 xx 10^12 = 3500000000000#
then you are able to do the calculation (use a calculator).The calculator gives the answer of
#0.000000061 = 6.1 xx 10^(-8)#
Hopefully this was helpful...
This is a sort of cheat method to make the numbers easier to deal with.
So we now have:
Using long division
Which is the same as:
