Answer 2

Hello! It seems you have provided a mathematical expression. Let's solve it step by step:

1. Start with the innermost parentheses: (469 - 398) = 71
2. Next, solve the multiplication: 42 * 21 = 882
3. Now, combine the results: 13 * 71 - 882 = 923 - 882 = 41

So, the result of the expression 13•(469-398)-42•21 is 41. However, the expression ends with ":63" which appears to be a typo or an additional symbol not part of the expression. If you can clarify its meaning or provide further context, I'd be happy to help.
