False.
eg
3 * 3 = 9 --> an odd number.
No. The square roots 8 are irrational, as are the square roots of most even numbers.
Just working with fractions if the coefficient of x is not an even number, however I would not call it a disadvantage because fractions are beautiful numbers.
Irrational numbers are infinitely dense. That is to say, between any two irrational (or rational) numbers there is an infinite number of irrational numbers. So, for any irrational number close to 6 it is always possible to find another that is closer; and then another that is even closer; and then another that is even closer that that, ...
For any given subset, yes, because there are an infinite number of irrational numbers for each rational number. But for the set of ALL real numbers, both are infinite in number, even though the vast majority of real numbers would be irrational.
No. because odd numbers don't have 2 as a factor but even numbers do. So it won't be a whole number.
what are the even square numbers between 10 and 70
No. The square roots 8 are irrational, as are the square roots of most even numbers.
yes
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....
It is true that the sum of 2 even numbers is never odd
Some of them are.
6
Yes. There is a pattern in square numbers. They are fun to play with.
True.
No, only square numbers have an odd number of factors.
Yes, that is true.
Even square numbers are even, by definition. Two even numbers multiplied together give an even number so no, they cannot multiply to give an odd number. You have to multiply an even number by an odd number to do this.
