Suppose the population of a town is 100,000 in 1999. the population increases at a rate of 4.5% every year. what will be the population of the town in 2005? round your answer to the nearest whole number

 ANSWER IS 127000
100,000*.045= 4500   FROM 1999 TO 2005 IS 6 YEARS
4500*6= 27000
27000+100000=127000

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.
