Question

6. Which of the following are empty sets? (i) A = (x | * E N. x + 5 = 5).
(ii) C = (x 1 x EW, x + 2 < 2). (u) E = (x | * EN, x2 + 4 = 0). (vii) G = (x | x is an even prime).​

Answer 1

Answer:

to find empty set or not

given = G=(x)x is an even prime

since we have 2 that is even and prime

so, G=(2)

hence G is not empty set
