Official Solution:

Statements (1) and (2) combined are insufficient. Consider \(X = Y = Z = 2\) (the answer is "yes") and \(X = Y = Z = \sqrt{2}\) (the answer is "no"). Do not assume that the numbers are all integers; the stem doesn't stipulate that.

Answer: E

While attempting this question, i tried all possible scenarios (keeping in mind that numbers may not be integers) and ultimately it boiled down to Either C or E.

Somehow could not think of \(\sqrt{2}\) as a possible option.

I was wondering if we take out the square root scenario, is there any other possible way one could still prove that using Both statements together are insufficient?
