Ok, I'm still trying to study math and now I have a goal in it! I'm going to start taking lessons to get a silly little degree... eventually, someday, maybe, perhaps (as if I'd ever)
Anyway I'm a bit baffled by this problem.
First example
sqrt(225) the answer is given as sqrt(225) = 15
That's pretty straight forward and after feeling accomplished for the fact that I managed to push the correct buttons in a calculator I get to do this one
2nd example
sqrt(75) but this time the correct answer was 3*sqrt(5)
Why is the answer shown this way in this case? I think it has something to do with the fact that the answer is an infinite decimal, but how am I supposed to calculate that sort of answers?
Kinda annoying that they give you the problem and the solution, but not the way you're supposed to get them.
