Hello,
For the following:
If x is a positive integer, which of the following CANNOT be expressed as n^2, where n is an integer?
A) x^5
B) X^2 - 1
C) sq. root (x^8)
D) X^2 + 1
E) sq. root (x^5)
OA: D
For B. the explanation from Veritas mentions that if x = 1 => x^2 - 1 = 1 - 1 = 0. I was just wondering if it is correct that 0 is an integer?
Thanks a lot,
Sri
