Let J be the set of positive integers, If H = {x: x∈J, x\(^2\) < 3 and x ≠ 0}, then
Answer Details
The set H consists of all positive integers x such that x² is less than 3 and x is not equal to zero.
The only positive integer that satisfies this condition is 1, because 1²=1 which is less than 3.
Therefore, the set H contains only one element which is 1, so the answer is H = {1}.
Option (a) is correct, and options (b), (c), (d), and (e) are incorrect.
It is important to note that the symbol ∈ means "is an element of", and the symbol ≠ means "is not equal to". The symbol J ≤ H is not a valid statement because J is not a subset of H.
