Question

write the following sets in the set builder form, {2, 4,8,16,32}

​

Answer 1

Hello

{2, 4, 8, 16, 32}

It can be seen that 2 = 21, 4 = 22, 8 = 23, 16 = 24, and 32 = 25.

∴ {2, 4, 8, 16, 32} = {x: x = 2n, n∈ N and 1 ≤ n ≤ 5}

Hope it helps.

Answer 2

Set builder form for the above mentioned set is as follows:-

{x : x is an element of R : x = x^n where n is a natural number}

Hope this helps.
