Question 893864: Hello.

I'm in need of your help. Well, to be honest, I don't have a sum to ask about, I just am in need of a formular to calculate complicated algebraic expressions and equations which have negative fractional exponents (please note that I said negative fractional exponents, not negative and fractional exponents). I'm in year 9, and I just love maths! I'm great at it and all I need is formulars. All I need now is for you to give me as much formulae as possible, and I'll be doing alright. Thanks!
