A licensed nurse practitioner is instructed to give a patient 2100 milligrams of an antibiotic over a period of 36 hours. If the
antibiotic is to be given every 4 hours starting immediately, how much antibiotic should be given in each dose? To answer this question, solve the equation 9x = 2100
You could do the negative square root of 16 and the negative square root of 25 to get -4 and -5. So this means the answer is negative square root of 20 is in between -4 and -5
