Question

If A = {x: x ∈ N, (x ^2 − 9)(x ^2 − 5) = 0} and B = {x: x ∈ N, x(x − 2)(x − 3) = 0} where N is the set of all natural numbers, then B × A is (a) {(2,3), (3, ,3)} (b) {(3,2), (3,3)} (c) {(0,3), (2,3), (3,3)} (d) {(3,0), (3,2), (3,3)}

Answer 1

Step-by-step explanation:

A={3}

B={2,3}

B × A={(2,3),(3,3)}
