Question 279100: Assume that the volume of the earth is 5 x 10^14 cubic meters and the volume of a bacterium is 2.5 x 10^-16 cubic meters. If the earth could be filled with bacteria, how many would it contain? (Round to one decimal place.)

The earth would contain 2+%2A+10%5E30 bacterium.

The formula is %285+%2A+10%5E14%29%2F%282.5+%2A+10%5E-16%29

5 / 2.5 = 2

10%5E14 / 10%5E-16 is equal to 10%5E%2814-%28-16%29%29 which becomes 10%5E%2814%2B16%29 which becomes 10%5E30.

your answer is therefore 2 * 10%5E30.
