Jake wants to enlarge his 12-foot by 14-foot garden. if he multiplies the dimensions by 2, how will the area of the garden be affected?

Area = L*W
Original Area = 12*14 = 168
Multiply the dimensions by 2 = 12*2 = 24 and 14*2 = 28
New Area = 24 *28 = 672

New Area divided by original area = 672/168 = 4

The garden will be 4 times bigger in area

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.
