Question

102-(155,4:14,8+2,1)*3,5

Answer 1

155.4:14=11.1
11.1+2.1=13.2
13.2*3.5=46.2
102-46.2=55.8
Ответ:55.8

Answer 2

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 apply these steps to the given expression:

Step 1: Evaluate what's inside the parentheses first.

155.4:14.8 + 2.1 = 155.4 / 14.8 + 2.1 = 10.5 + 2.1 = 12.6

Step 2: Perform the multiplication.

102 - 12.6 * 3.5

Step 3: Perform the multiplication.

102 - 44.1

Step 4: Perform the subtraction.

102 - 44.1 = 57.9

So, the final result is 57.9.
