Hello and sorry if I'm not posting in the right section, but I have the following problem: If a and b are rational numbers and sqrt from a+b does Not equal 0, how do I demonstrate that sqrt from a-b does not equal 0?
no, i'm sorry i meant a+sqrt(b) !=0 and prove a-sqrt(b)!=0, where sqrt stands for square root and != for does not equal i'm sorry for my terminology, but i'm not used to the english one
