The base of a parallelogram is (2+3)units and the corresponding height is (2−3)units. Find the area of the parallelogram in terms of .What will be the area of the parallelogram if =units?

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.
