Answer 3

To solve the given mathematical expressions, let's break them down one by one:

1. 40 - 2: The result is 38.

2. 75 - 4: The result is 71.

3. 5 + 12 * 5 - 4: To solve this expression, we follow the order of operations (PEMDAS/BODMAS). First, we perform the multiplication: 12 * 5 = 60. Then, we perform the addition and subtraction: 5 + 60 - 4 = 61.

4. 104 - 8: The result is 96.

5. 63³ - 2²: To solve this expression, we need to perform the exponentiation first: 63³ = 63 * 63 * 63 = 250,047. Then, we subtract the squared value: 250,047 - 2² = 250,047 - 4 = 250,043.

6. 101 - 8 - 2 ÷ 9 + 4: Again, following the order of operations, we perform the division first: 2 ÷ 9 ≈ 0.2222 (rounded to four decimal places). Then, we perform the subtraction and addition: 101 - 8 - 0.2222 + 4 = 96.7778 (rounded to four decimal places).

7. 112 - 17 - 33 + 3: Performing the subtraction and addition: 112 - 17 - 33 + 3 = 65.

8. 8 - (-6) * 5 + 10: Following the order of operations, we first perform the multiplication and the negation: -6 * 5 = -30. Then, we perform the addition and subtraction: 8 - (-30) + 10 = 48.

So, the results of the given expressions are:

1. 38
2. 71
3. 61
4. 96
5. 250,043
6. 96.7778
7. 65
8. 48
