Question

3,8•(8,57+9,585÷4,5)​

Answer 1

Ответ:

1)9.585÷4,5=2.13

2)8.57+2.13=10.7

3)10.7×3.8=40.66

Answer 2

To calculate the expression 3.8 * (8.57 + 9.585 / 4.5), 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 case, we'll start with the parentheses:

1. Inside the parentheses, perform the division first: 9.585 / 4.5 = 2.13

2. Now, add the result from step 1 to 8.57: 8.57 + 2.13 = 10.7

3. Finally, multiply the result from step 2 by 3.8: 3.8 * 10.7 = 40.66

So, 3.8 * (8.57 + 9.585 / 4.5) equals 40.66.
