the population of a bacteria coleny, p, is doubling every day,d, according to the equation p=2^d. five days later, the population of another bacteria colny, q, is quadrupling everyday,d, according to the equation q=4^d-5. when will the populations of the two bacteria be equal?
what does this question mean explain plz im sooo lost :( do i put 10 for p=2^d --> p=2^10?
