True.
It depends, many people do count 0 as a natural number, but MOST do not. So for most HS text book, the answer is NO, all whole numbers are not natural numbers and the reason is 0 is a whole number but not a natural number.
is every multiple of five a composite number true or false
No because 2 is an even number which is also a Prime number that has only two factors which are itself and one.
False
True. I think each and all mean the same thing in this context.
False. eg 3 * 3 = 9 --> an odd number.
They are all square numbers, and 170 isn't a square number. Very easy..
False
One possible conjecture is that each square number up to 1000 has 4 factors. The conjecture is manifestly false, but it is still a conjecture.
False. It is true for every positive number greater than 1, this includes non-integers, and any number less than zero. Numbers between 0 and 1 have squares smaller than their principal square root.
False
False because 2 is an even number which is also a prime number.
False. 22 = 4
False. 22 = 4
The is false. "the whole number" is a single number while "the set of natural numbers" is a set. A single number cannot be equal to a set.

if by Numbers you mean Integers, then the answer is TRUE. if it is real numbers, then it is false.
