and my last problem i need help with. i don't know how to even begin settin the problem up to figure out the answer.
E coli, a typical bacterius, is about 2 micrometers long. how many E coli could you line up, end-to-end, in one mm?

• Math -

2*10^-6 m long
1 mm = 10^-3 m

2 * 10^-6 n = 10^-3
2 n = 10^3 = 1000
n = 500

would you please explain how you got this answer? Im not sure what the calculations are that you used. thank you so much.

What does ^ stand for?
