Answer 3

To solve this expression step by step, 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). Let's break it down:

1. First, solve what's inside the parentheses: 16:4 = 4 42:7 = 6 So, the expression becomes: 270:9 * 7 - 360:(4 + 6*6 + 15)

2. Next, within the parentheses, do the multiplication: 6 * 6 = 36 So, the expression becomes: 270:9 * 7 - 360:(4 + 36 + 15)

3. Still within the parentheses, do the addition: 4 + 36 + 15 = 55 So, the expression becomes: 270:9 * 7 - 360:55

4. Now, continue with multiplication and division from left to right: 270 ÷ 9 = 30 360 ÷ 55 ≈ 6.5455 (rounded to 4 decimal places)

5. Finally, perform the remaining operations from left to right: 30 * 7 - 6.5455 ≈ 210 - 6.5455 ≈ 203.4545 (rounded to 4 decimal places)

So, the result of the expression is approximately 203.4545.
