Re: Equations with parenthesis?
Do you know you are right? Would you bet on it?
In mathematics, you don't understand things. You just get used to them.

Re: Equations with parenthesis?
Of course not. If I were sure of my answers I would not waste your time asking for help.
I was not being sarcastic, I really do not see the other mistake you mentioned.

Re: Equations with parenthesis?
How poetic of you...
How about: -2x²y³ · 14x²y³? No parenthesis this time...

Re: Equations with parenthesis?
No, biblical not poetic.
This problem is no different. Just remember when you multiply two quantities that have the same base like x^2 * x^4, you add the exponents. So go ahead.
