Final answer:
To evaluate the expression [8+(10-:5)]^(2), we follow the order of operations and simplify the expression step by step. The final result is 169.
Step-by-step explanation:
To evaluate the expression [8+(10-:5)]^(2), we follow the order of operations, which states that we should perform any calculations inside parentheses first. Inside the parentheses, we have (10-:5), which means we subtract 5 from 10. So, (10-:5) = 10 - 5 = 5.
Next, we simplify [8+(10-:5)] to [8+5]. Now, we add 8 and 5 to get 13. So, the expression becomes 13^2.
Finally, we evaluate 13^2, which means we multiply 13 by itself. 13^2 = 13 * 13 = 169.
