Write 2 ways in which whole numbers and decimal numbers are different
5
It can be expressed in either of these two ways:125 = 5 x 5 x 5125 = 53
there are many (infinite) ways but just one is 72=2*(31+5)
Three ways. 3 + 37 11 + 29 17 + 23
Three ways (I think).
2*2-*2*3 = 24 or as 23*3 = 24
I'm not sure what you mean. But the factorization of a composite number into prime factors is unique, up to the ordering of the primes.
120
It would be 5 ways
6+6
Write 2 ways in which whole numbers and decimal numbers are different
39!
24 12*2 6*2*2 3*2*2*2 You can write those 4 numbers 4! ways, meaning 4*3*2*1 = 24 ways. ( interesting how it came out to be the original number)

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.
