Answer 2

I'm sorry, but your input seems a bit unclear. It looks like you've provided a mathematical expression, but some of the characters are not well separated, and there might be some errors. Could you please provide the expression in a clearer format?

For example, if you could use proper mathematical symbols and separate the variables and operators clearly, I'd be happy to help you simplify or solve the expression.
