Answer 2

To calculate the expression 17^2 - 34 * 7 + 7^2, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In this expression:

1. Calculate 17^2 (17 squared): 17^2 = 289

2. Calculate 7^2 (7 squared): 7^2 = 49

3. Multiply 34 by 7: 34 * 7 = 238

Now, we can substitute these values back into the expression:

289 - 238 + 49

Now, perform the subtraction and addition from left to right:

289 - 238 = 51 51 + 49 = 100

So, the value of the expression 17^2 - 34 * 7 + 7^2 is 100.
