Bacteria grown in a lab experience what is called an 'exponential phase' of population growth. Suppose that, during this phase, a colony of Mycobacterium tuberculosis you are growing has a per capita growth rate, r, of 0.063 per hour. If the size of your colony at the start of the exponential phase is 0.25 billion cells, then approximately how large will it be in 48 hours?

complete the square on the right side of the equation;
