Think of their prime factorizations. A squared number will always have paired prime factors. When they have no prime factors in common, like 4 (2 x 2) and 9 (3 x 3), the LCM will be their product, 2 x 2 x 3 x 3 or 36 (6 squared). When they have prime factors in common, like 36 (2 x 2 x 3 x 3) and 225 (3 x 3 x 5 x 5), the LCM will still have paired factors: 2 x 2 x 3 x 3 x 5 x 5 or 900 (30 squared)
No, but only in the case of the number 1 (12=1) are square numbers odd.
True.
No. The square of an odd number will be odd and the square of an even number will be even.Examples:5x5=2511x11=12115x15=2254x4=168x8=6416x16=256
The square root of a composite number is not always an irrational number. e.g. 4 is a composite number and its square root is 41/2 = 2, which is rational number.
There are infinitely many possible answers. The smallest set of numbers is (9, 16, 144, 169)
Yes
That's the "square" of the number. With counting numbers, the square will always be another counting number.

=== === No === ===
when you subtract one square number with another the answer is 16 what are the two numbers
4 and 9
The square numbers are: 16-4 = 12
Another square number.
all of the numbers, except the numbers 1 and below
No, but only in the case of the number 1 (12=1) are square numbers odd.
No, and I can prove it: -- The product of two rational numbers is always a rational number. -- If the two numbers happen to be the same number, then it's the square root of their product. -- Remember ... the product of two rational numbers is always a rational number. -- So the square of a rational number is always a rational number. -- So the square root of an irrational number can't be a rational number (because its square would be rational etc.).
