Matchswatch asks what the prime factors of 80 are in ascending order, so I type
2 2 2 2 5

It tells me I'm wrong?
Should this be flagged as an educational crime???

If you have a suggestion please make it, the question is too simple to read again.

My suggestion was to re-read the question as you haven’t answered the one you have written in the original post correctly.

I have tried 2*2*2*2*5 , 2^4 *4, 2^4 * 5^1, I tried getting up on the table and singing the answer... Do you have any suggestions which don't imply i have not read the question>???

The question you have stated is what are the prime factors not prime factorisation

Thank you. The question is literally...

Express 80 as the product of its prime factors.
Write the prime factors in ascending order.

Thank you for your suggestions so far. I am at a loss to understand what it is asking me to do.

PS I am a researcher in Quantum statistics. My daughter asked me to look at this.

You are giving the answer as the factorisation -it just wants the factors on their own.
So instead of 2 2 2 2 5
It would just be 2 5

Perhaps-I just read the question you typed out and it does seem to be asking for the factorisation...

(It possibly includes 1 but don’t know if they discount 1 or not cos sometimes it’s a prime number and sometimes it’s not)

I've tried that, just typing the factors but still no go. I've done things with brackets, indices, spaces, I even considered inputting using LaTex.... I wish I could show you a screenshot, It really is most perplexing.

Also, You have been very helpful, thank you.

Sounds totally frustrating!
are you using * or X ?

You can add a screenshot to the post if it would help?

Ta Daaaa! Thank you so much. It uses x for multiplication!

This is all very reasonable I suppose, but I have been writing FORTRAN programs for 30 years!

You are my savior, I would never have seen that in a million years.

I am at your disposal if you require assistance with anything math or physics like.

Would it be too much to bother you with one more similar issue on Mathswatch?
