Answer 2

1) 16,2:2,7+2,28=6+2,28=8,28
2)8,28×4,5-38,639=37,26-38,639=-1,379

Answer 3

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's break down the expression step by step:

1. (16,2:2,7 + 2,28) = (16 + 2,28) = 18,28 (Note: The comma here seems to be used as a decimal separator.)

2. 18,28 * 4,5 = 82,26

3. 82,26 - 38,639 ≈ 43.621

So, the result of the expression is approximately 43.621.
