Answer 3

I'm sorry, but I'm not sure what you are asking. "5в квадрате+2в квадрате" does not form a complete question or statement.

If you meant to ask for the solution to the expression "5в квадрате+2в квадрате", then that translates to "5v² + 2v²" in English and can be simplified by combining like terms to get:

5v² + 2v² = 7v²

So the solution is 7v².
