Suppose that when your friend was born, your friend’s parents deposited $7,000.00 in an account paying 4.5 percent interest compounded quarterly. what will the account balance be after 15 years?

7000x 4.5 % =$ 315.00 interest quarterly
$315÷3=$105 monthly (interest)
$105 x 12 (months) = 1,260 (total of interest in 1 year)
1,260 × 15 (years) = 18,900 ( total of interest in 15 years )
18,900 +7,000= 25,900 Ans//

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.
