Ok, so I appreciate that this isnt a difficult question, but I am having some serious problems here...
After years of being afraid to learn maths, I have finally bitten the bullet and decided to go back to school. I want to work with sciences, so I need a strong background in maths. To prepare for going back to school (there are some paperwork issues stopping me applying immediately) I am currently re-learning using the book Algebra Demystified (I plan to work on other books in the series after im done with this one, until I am able to go to college).
Anyway, im stuck on roots, particularly simplifying roots.
I dont really understand the process, and I dont really understand WHY we simplify roots. Basically, the whole thing has gotten me a bit stumped, and i wondered if I could ask here for some help?
Thanks in advance, and im so sorry if this is a bit garbled... I will try to clarify it a bit if needed?
