if either x = -3 OR y = 2 is there the statement is true

6. BAdhi

product of two even numbers will give an even number so its closed under multiplication product of two prime numbers will not give a prime number (since the resultant number can be divided from one of the prime numbers that you began with) product of two negetive numbers will not give a negetive number (two negative numbers multiplied will result in a positive number) $$x^3 \times y^3 = (xy)^3$$ xy is a perfect cube
