What power of 2 is approximately 1,000,000?

Please show us what you have learned about exponential functions and logarithms.

Please post the EXACT problem (along with your work) as it was given to you.

As posted, the problem CANNOT be solved.

Good point. I was implicitly assuming that "bacteria" was intended to mean "bacterium" (that is, singular, a common mistake for Latin words like this), so that we start with one. Hopefully the original problem didn't make such an error, but explicitly stated how many there were at the start.
 
If you start with a million then the time to have 1,000,000 will be 0 hours.
If you start with 500,000, then it will take 1 hour in order to reach 1,000,000.
If you start with 250,000, then it will take 2 hours in order to reach 1,000,000.

Do you see that you need to inform us how many bacteria you started with?
