Answer 2

To solve this expression, 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, there are no parentheses or exponents, so we'll perform the multiplication and division first, and then the addition:

56 + 76 + 34 + (23 × 43 ÷ 54) + 65 + (23 ÷ 87)

First, calculate the multiplication and division:

23 × 43 = 989 989 ÷ 54 ≈ 18.35 (rounded to two decimal places) 23 ÷ 87 ≈ 0.26 (rounded to two decimal places)

Now, substitute these results back into the original expression:

56 + 76 + 34 + 18.35 + 65 + 0.26

Finally, add all these numbers together:

56 + 76 + 34 + 18.35 + 65 + 0.26 ≈ 250.96

So, the approximate value of the expression is 250.96.
