Answer 1

Divisible means "can you divide by and have no remainder. So, 8 is divisible by 2 because 8/2 is 4. However, 8 is NOT divisible by 3 because 8/3 is 2 with remainder of 2.

Square numbers are 1*1, 2*2, 3*3, 4*4, etc. Take a number, multiply it by itself.

What does number 1, 4, 9, 16 suggest? For one, it is never ending. It goes on forever. For another, it's a number raised to the power of 2. Look at the chapter in your book. It should tell you what kind of answer they are looking for.
