Answer 2

It seems like you've provided a mathematical expression, but there are some formatting issues that make it a bit unclear. The symbols "а3" and "в" might be variables, but I'm not sure. Could you please clarify the expression and provide any missing information or correct formatting? This way, I can assist you better.
