Answer 2

It looks like you've provided some symbols and values, but it's not clear what you're asking for or what context you need assistance with.

The symbols "M(роз)" and "w(реч)" are not standard mathematical or scientific notations that I'm aware of, and without more context, it's difficult to understand what you're trying to convey.

If you could provide more information or clarify your question, I would be happy to try to assist you further.
