Q. Prove that relation R on the set N x N defined by a,b R c,d⇌a+d=b+c for all a,b, c,d∈ N x N is an equivalence relation.
[] represent greatest int function....
(a) (b)
(a) (1, 2) (b) (–10) ∪ (1, 2)
(c) (1, 2) ∪ (2, ∞) (d) (–1, 1) ∪ (1, 2) ∪ (2, ∞)
remainder when x is divided by y
= quotient obtained when x is divided by y.
SQ (x) = the smallest integer bigger than the square root of x.
If x = 12, y = 5, then the value of the expression SQ is
