Picture it using actual numbers.

If you had sqr(9) on one side, what then?
Square both sides.
Your sqr(9) magically becomes just "9", because:

sqr(9) X sqr(9) = 9

Remember what BugMeister said:

...what you do to one side of the equation, you must also do to the other...
Whatever is on the other side is also squared and becomes {itself} X {itself}

Clicked the wrong thing while replying and had to start over. It took you a lot less words to say what I was trying to tell him.

@THW:I didn't want to give him the result...rather have him recall basic rules. sorry if in doing so I spoiled your plan.
I'm actually enjoying this...haven't had the need to recall those calculations for pretty much an eternity now either

@Prof: my explanation is shorter... true but some ppl might understand better if they go the long way around

Perhaps I should register with Big Y (they run a homework helpline over here)

Math is just a set of rules. Play the game right and use the rules in their proper order and you'll win every time.

(Easier said than done, I know.)

It's no fun, but LOTS of practice is the best idea. You wouldn't shoot one free throw, sink it, then decide you had it down pat. But doing it over and over and over and...

No, what he's saying is in Wisconsin, people don't need to practice at anything. We always get it done right the first time.
