Answer 1

To evaluate the expression, we can simplify each squared term first.

9 squared is equal to 81.
2 squared is equal to 4.

Thus, the expression becomes:

(81 - 17) ÷ 4

Next, we can subtract the numbers in the brackets:

81 - 17 = 64

Finally, we can divide the result by 4:

64 ÷ 4 = 16

Therefore, the value of the expression is 16.
