List all the elements of each of the sets given below.D = {x : x = n2 , n ϵ N and 2 ≤ n ≤ 5}.

Answer»

Here, x = n² and 2 ≤ n ≤ 5

∴ n = 2, 3, 4, 5

[it is given that n is less than equal to 2 and greater than equal to 5] If

n = 2, x = (2)² = 4

n = 3, x = (3)² = 9

n = 4, x = (4)² = 16

n = 5, x = (5)² = 25

So, D = {4, 9, 16, 25}
