the product of the squares of two positive integers is 9 . how many pairs of positive integers satisfy this condition ?
"ans : b - 1 pairs ( x ˆ 2 ) ( y ˆ 2 ) = 9 [ square root both sides ] xy = 3 3 = 1 x 3 , 3 x 1 cancel the repeats this leaves us with exactly 1 options . hence , b"
subtract(add(const_2, const_3), const_2)
