today in my algebra class my teacher was going over the pythagoreum theorum and gave us a few problems to work on ind i saw this. Side A=6 times 2 squared Side B=6 Side C=X
Solve for x. when we went over the problem he used the term radical to explain the way to find side A and said it was something to with 6 radical 2 what in the world is a radical or did i mishear what he said? is it not even a square root or anything to do with squares? i dont know step by step instructions would help but links are also welcome

This sign √, you should have learned this in Algebra 1.

A radical is the same thing as a square root sign.
So 6 radical 2 is the same as 6 sqrt 2

to simplify it you can do 6 to the 2nd power is 36 multiply by 2 which eaquals 72. the square root of 72 is the same thin as 6 radical 2. it works with any problem like that.

In this context he meant square root. But radical technically is the little checkmarklike symbol. A radical is used for all roots not just square.

The term "radical" in the sense your teacher used it means square root: â. ("Radical" can mean either the operation of taking the square root, or the symbol â itself.)
More generally, "radical" can refer to any nth root. (Cube roots, 4th roots, etc.)
