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.
False
All prime numbers are odd except for the number 2.
A prime number is a number that can only be divided by 1 and itself. Not all odd numbers are prime numbers; for example 9, 15, 21 can be divided by more than one and itself.
is every multiple of five a composite number true or false
False. eg 3 * 3 = 9 --> an odd number.
False
False
They are all square numbers, and 170 isn't a square number. Very easy..
False because 2 is an even number which is also a prime number.
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. 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.
