Answer 2

It seems like you've provided a mathematical expression, but the expression is not entirely clear due to the formatting. Could you please provide more context or clarify the expression? Specifically, the use of colons and parentheses is a bit confusing. If you can provide the expression using standard mathematical notation, I'd be happy to help you understand or simplify it.
