Unformatted text preview: starting and ending numbers of cells. By dividing both sides by N you get: N t /N =2 g Now if you were good at log 2 you could solve this easily  it would be log 2 (N t /N )=g, but most of us think in terms of log 10 , so you can either look in your old math book or take it from me that this translates into [log 10 (N t /N )]/log 10 2=g of course, you remember that the log 10 2=0.301, so the formula roughly becomes [log 10 (N t /N )]/0.3=g g/t is the growth rate, and t/g is the doubling time....
