Here's a DS question that I found in my book:
The answer is supposed to be B but I think it's E, right? In statement #2, if m = 1, then r = 1 and √r isn't an integer. But if m = 2, r = 4 and √r = 2, which is an integer, so statement 2 is insufficient, right? :roll:If r > 0, is √r an integer?
(1) r² is an integer.
(2) r = m², where m is an integer.
