Oh, dude, 22 is like a VIP club that only lets in numbers that can divide it without any drama. So, numbers like 1, 2, 11, and 22 are totally on the guest list. It's like the number 22 is just chillin', waiting for these numbers to show up and party with it.
Write the prime factors as powers. In a square number, each prime number appears an even number of times - i.e., an even power. Examples: 4 = 22 (even power, this is a square) 144 = 24 x 32 (all powers are even, this is a square) 12 = 22 x 3 or 22 x 31 (3 has an odd power so it is not a square) (If a number is a perfect square, that is equivalent to saying that its square root is a whole number.) * * * * * In this case there is a particularly fast method. The number ends in 0 so 10 must be a factor of the number. That is to say, 2 and 5 must be prime factors of the number. If it is a square then 22 and 52 must be factors of the number ie 22 x 52 = 100 must be a factor. But if 100 is a factor, the number must end in 00. It does not so it cannot be a square.
A negative number multiplied by a positive number gives a negative result, so -22 times 22 is -484
