Question

(-9,18/3,4-3,7)*2,1+2,04=? с решением)))

Answer 1

Ответ:

(- 9,18 : 3,4 - 3,7) * 2,1 + 2,04 = - 11,4

1) - 9,18 : 3,4 = - 2,7

2) - 2,7 - 3,7 = - 6,4

3) - 6,4 * 2,1 = - 13,44

4) - 13,44 + 2,04 = - 11,4

Answer 2

To solve this expression, let's follow the order of operations (PEMDAS/BODMAS):

P - Parentheses first E - Exponents (none in this case) MD - Multiplication and Division (from left to right) AS - Addition and Subtraction (from left to right)

The expression is:

(-9, 18/3, 4 - 3, 7) * 2, 1 + 2, 04

Step 1: Simplify the expression inside the parentheses: (-9, 18/3, 4 - 3, 7) = (-9, 6 - 3, 7)

Step 2: Perform the subtraction inside the parentheses: (-9, 6 - 3, 7) = (-9, 2, 3)

Step 3: Multiply the result by 2,1: (-9, 2, 3) * 2,1 = -19, 83

Step 4: Add 2,04 to the previous result: -19, 83 + 2, 04 = -17, 79

Therefore, the final result of the expression is -17.79.
