Why are some odd numbers composite?
Some. Any product of a set of odd numbers will be odd. To be even, a composite number must have at least one even factor. Therefore odd composite numbers must exist.
If the product of two numbers are even then the two numbers must both be even?
No. If you have an odd number (for example 5) and an even number (say 2) and you multiply them together, you will get an even number (10). Therefore, just because the product of two numbers are even does not make both the numbers being multiplied together even (although at least one must be).
Is the product of an even number of negative numbers positive?
Yes because the product of each pair of negative numbers must be positive.
If the product of two numbers is even then the two numbers must be even.?
no eg: 9x4=36
What is the product of a digit?
In order to have a product, you must have a multiplication problem which requires two numbers to be multiplied. For example, in 2 * 3 = 6, 6 is the product.
If the product of two numbers is even then the two numbers must be even?
At least one of the two numbers has to be even, but both can be even.
How do you know a product of any 2 numbers greater than 1 must be a composite number?
Because that product would have both of the two numbers as factors, giving it at least a total of 4.
If the product of two numbers is even then the two numbers must be even right?
Not necessarily, but at least ''one'' of them must be even, unless the two numbers are both the (irrational) square root of the same even number.
Why are some odd numbers composite?
Some. Any product of a set of odd numbers will be odd. To be even, a composite number must have at least one even factor. Therefore odd composite numbers must exist.
If the product of two numbers are even then the two numbers must both be even?
No. If you have an odd number (for example 5) and an even number (say 2) and you multiply them together, you will get an even number (10). Therefore, just because the product of two numbers are even does not make both the numbers being multiplied together even (although at least one must be).
If the product of two numbers is even does that mean the two numbers must be even?
No. It only means they weren't both odd (or another way, that at least one of them was even). An example would be 8 x 9 = 72; the product is even, yet one of the numbers was odd.
What is the product of two numbers is zero?
One or both of the numbers must be zero.
Is the product of an even number of negative numbers positive?
Yes because the product of each pair of negative numbers must be positive.
What two even numbers total a odd product?
None. The sum or product of any two even numbers must be even.
How find 2 numbers with a sum of 23 and product of 132?
as 132 is an even number at least one of the two numbers must also be even 12 + 11 = 23 12 x 11 = 132
If the product of two numbers is even then the two numbers must be even.?
no eg: 9x4=36
What property is used for 13n equals 0?
The property used for the equation 13n = 0 is the zero product property. This property states that if the product of two numbers is zero, then at least one of the numbers must be zero. In this case, if 13n equals 0, then n must be 0 because any number multiplied by zero equals zero.
