Answer 2

Answer:

A = {2, 4, 6, 8} and

B = {2n : n ∈ N and n < 5}

(ii) M = {X : X ∈ W and x + 3  < 8} and

N = {Y: Y = 2n – 1, n ∈N and n < 5}

(iii) E = {X : X2 + 8X – 9 = 0} and

F = {1, -9}

(iv) A = {X : X ∈ N, X < 3} and

B = {Y : Y2 – 3Y + 2 = 0}

Note : Two sets are equal, if both the sets have same (identical) elements.
