Answer 3

To solve this expression, you can use 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 your expression:

52 * 71 + 28 * 71 - 40 * 71 - 71

You can first simplify the multiplications:

52 * 71 = 3692 28 * 71 = 1996 40 * 71 = 2840

Now, the expression becomes:

3692 + 1996 - 2840 - 71

Next, perform the additions and subtractions from left to right:

3692 + 1996 = 5688 5688 - 2840 = 2848 2848 - 71 = 2777

So, the answer is 2777.
