No; most are not, not even close. 2 is not a square, 6 is not a square, 8 is not a square, 10 is not a square, 12 is not a square, and 14 is not a square, just for starters.
Only a very small proportion of even numbers are squares: 4, 16, 36, 64, 100, 144, 196, 256, 324, 400....
No - all squares of even numbers are even - while all squares of odd numbers are odd.
No
No. The square roots 8 are irrational, as are the square roots of most even numbers.
The factors of all numbers can be written in pairs. With square numbers, one of those pairs is the same number twice. When listed singly, square numbers have an odd number of factors. All others are even.
No.
No. Perfect square numbers have an odd number of factors.

All non-even numbers are odd. All squares of even numbers are even. All squares of odd numbers are odd. Therefore all numbers which are odd and not the square of an odd number are the solution set. It contains: {3, 5, 7, 11, 13, 15, 17, 19, 21, 23, 27, 29, 31, ...}
No, all perfect square numbers are not even numbers. Eg. the square of 3 is 9. (32=9) To generalize the proof: If p is odd then p=2n+1 and p2=(2n+1)2=4n2+4n+1=2(2n2+2n)+1 So odd numbers have odd square
All numbers, even imaginary or complex ones, have squares.
what are the even square numbers between 10 and 70
yes
All nonzero numbers have factors. Some factors are even numbers, some factors are odd numbers.
False. eg 3 * 3 = 9 --> an odd number.
