Answer 3

Let's solve the expression step by step:

1. Start by evaluating the expressions inside the parentheses: 42 + 82 = 124 102 + 92 = 194

2. Now, rewrite the expression with the results of the parentheses: (124) - 10(194) + 220

3. Next, perform the multiplication: -10(194) = -1940

4. Now, substitute the result back into the expression: 124 - 1940 + 220

5. Finally, perform the addition and subtraction operations from left to right: 124 - 1940 + 220 = -1796 + 220 = -1576

So, the value of the expression (42 + 82) - 10(102 + 92) + 220 is -1576.
