To simplify the expression (10-6) ² + 8 - 2 ², we start by evaluating the terms inside the parentheses: (10-6) ² simplifies to (4) ², which is equal to 16. Similarly, 2 ² is equal to 4.
So the expression becomes:
16 + 8 - 4
Next, we solve from left to right using the order of operations:
16 + 8 = 24
24 - 4 = 20
Therefore, the simplified expression is 20.
