There are many ways to do prime factorisation for 20. It is not prime as it has more than 2 factors. The beginning of the prime factorisation is correct, but it is incomplete. These are two ways to complete it. 20 4x5 2x2x5 or 20 2x10 2x2x5 You have to continue using factorisation on all the numbers until all the numbers are prime. The prime numbers will always be the same if it starts with the same original number.

is it 8

1x20 2x10 4x5

4+5-4x5 First you do 4x5=20 Then 4+5=9 So you have 9-20=-11 Your answer is -11

having the property that one term operating on a second is equal to the second operating on the first, as an example: 4x5=5x4 or 5x4=4x5 RATE MY ANSWER THE BESTEST OF ALL!!!!

All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. All the factors are prime. 2 x 3 x 5 x 7 = 210 That's the prime factorization of 210.

The factors pairs of 20 are 1x20, 2x10, and 4x5 so 20 has 6 factors and 5 proper factors.

The Commutative Property (of Multiplication) says that 4x5 = 5x4. So, If 4x5 = 20, then 5x4 will also be 20.

120 4x5= 20x6=120 so this number has those as factorsw. The smallest such is 60.

4x5=20 cs if you add 5 four times 5+5+5+5 it equals 20.

Here is one factor tree of 300: 300 20 x 15 (4x5) x (3x5) ((2x2)x5) x (3x5) You have reduced it to prime numbers, so you are finished. The factors of 300 are 2, 2, 3, 5, and 5.

something like 5x4=4x5.

4X90=360 4X5=20 6X5=30

Let's do 20 first.20 can be written as 4x5. Note that 5 is prime but 4 is not. So write 4 as 2x2.The prime factorization of 20 is 2x2x5.Now for 60, we have 3x20.We can use what we just did and write the prime factorization of 60 as2x2x3x5.
