For a number to be a perfect square, the number's square root has to be a whole number. 9 is a perfect square because its square root is a whole number, 3. If the square root of the number is a decimal, then it is not a perfect square. For example, 13 does not divide evenly so it not a perfect square.
-1 is an odd number but not a perfect square.

The largest perfect square less than or equal to 160 is 144, which is (12^2). The next perfect square, (13^2), equals 169, which exceeds 160. Thus, 144 is the largest perfect square within that range.
9
It is both.13 is the square of +/- 3.6056, approx. However, since it is not the square of an integer, it is not a perfect square.It is also the square root of 169.
How about 7*7 = 49 because 4+9 = 13
