4xy
The GCF is 4xy
4(2x + 3y)(2x + 3y)
48xy
To simplify the expression (6x \cdot 8y - 3 - 7y), first, multiply (6x) and (8y) to get (48xy). Next, combine like terms by rearranging the expression: (48xy - 3 - 7y). Thus, the simplified expression is (48xy - 7y - 3).
lcm(16xy, 3x) = 48xy
9x2 + 48xy + 64y2 = (3x + 8y)2. Since it is a squared number cannot be a prime. We can say that as a perfect square number, it is formed by the sum of 1 and some prime numbers (excluded 2), i.e 1 + 3 + 5 + 7 + 11 + ... n, where n is a prime.
