for 10 years the population of a city incrases in a pattern that is approximately exponential. Using exponential modeling, you find a finction p(t) to descibe the population where p in the population (in thousands). of the city in year t. your function uses an intial value of 15 and 6.4% and 6.4% annual growth rate. what is a resonable prediction for the future pupulation in the city?

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
