How do you find whether a number is a perfect square by using its prime factors?
In the prime factorisation of the number, each factor must appear an even number of times.In the prime factorisation of the number, each factor must appear an even number of times.In the prime factorisation of the number, each factor must appear an even number of times.In the prime factorisation of the number, each factor must appear an even number of times.
Are there two prime numbers that multiply together to equal 168?
No. In order for two factors (i.e. two numbers multiplied together) to result in an even number, at least one of the factors must be even. Except for "2" all prime numbers by definition must be odd numbers. 168/2 = 84. 84 is not prime. Therefore you are looking for 2 odd factors of 168. But this is a fruitless search as 2 odd numbers multiplied together will never result in an even number.

Is the product of all prime numbers odd?
No. Since 2 is a prime and any number multiplied by an even is even, the product of all primes must be even.

How do you solve a prime number?
to answer a prime number you must find a number that goes into it and that divides by itself :)
What number is a multiple of 4 and 6 and the two digits must make a prime number when added together?
I believe the number you are looking for is 96.
What number is both a prime number and a multiple of 3?
No number that is a multiple of 3, can be a prime number. A prime number must only be divisible by itself and 1. It cannot be divisible by any other number. Therefore if it is a multiple of 3, then it must be divisible by 3 and hence, not a prime number.
Reasons why square numbers are said to be composite numbers?
Prove the opposite.Assume that a square number is prime.A square number is one that is a product of a number multiplied by itselfA prime number is one that has no factors other than itself and 1.For a prime number to be square, the only choice is for it to be 1*1=1Since 1 is not a prime number, there is a contradiction, and the original premise is false.Therefore, all square numbers must be composite.â–
