1. Hi. I am asked to leave the answer in exact form. What does it mean?

I have f =sqrt{60}
Should I leave it likes this or make 2sqrt{15}?
Thanks
2. like this f =sqrt{60}

exact means full, unchanged form.

Either is fine. They are both exact. Just don't give it as 7.76 or whatever.

Uh, no.
4. Thank you for replies
5. It is depressingly common for people to think that exact means all the digits on the display. Of course is much better if written but this would be simplest exact form.

I don't think I could leave it as but (in an exam) there is always a risk that if you put in extra lines that do unnecessary tidying up, you might make an error and you are wasting time.
