Write the following in roster form

{x ∈ N : 4x + 9 < 52}

Write the following in roster form.

{x : `(x − 4)/(x + 2)` = 3, x ∈ R – {– 2}}

If n(P(A)) = 1024, n(A ∪ B) = 15 and n(P(B)) = 32, then find n(A ∩ B)

If n (A ∩ B) = 3 and n(A ∪ B) = 10, then find n(P(A ∆ B))

Choose the correct alternative:

If A = {(x, y) : y = e x , x ∈ R} and B = {(x, y) : y = e^−x, x ∈ R} then n(A ∩ B) is

Choose the correct alternative:

If n((A × B) ∩ (A × C)) = 8 and n(B ∩ C) = 2, then n(A) is

Choose the correct alternative:

If n(A) = 2 and n(B ∪ C) = 3, then n[(A × B) ∪ (A × C)] is
