Is the square root of 9 a natural number, a integer, a rational number or a irrational number? ?

Question

I know that the square root of nine is 3 but the question asks for me to put the square root of nine (without reducing it).

Answer 1

yes, yes, yes, no.

Answer 2

It doesn't matter how you write it. It's still the same number.

"√9" and "3" are completely interchangeable--they mean exactly the same thing.

3 is a natural number, an integer, and a rational number (because it can be written 3/1), but not an irrational number (because it's rational).

So √9 is a natural number, an integer, and a rational number (because it can be written 3/1), but not an irrational number (because it's rational).
