Answer 1

Ответ:

$- 27 - \sqrt{2}$

Пошаговое объяснение:

$2 + 2 \times 2 \div 2 - \sqrt{2} + 22 - 10 + 7 - 5 \times 10 = 2 + 1 \times 2 - \sqrt{2} + 22 - 10 + 7 - 50 = 2 + 2 - \sqrt{2} + 22 - 10 + 7 - 50 = - 27 - \sqrt{2}$

Answer 2

Answer 3

To solve the expression 2+2×2÷2-√2+22-10+7-5×10, we follow the order of operations (also known as PEMDAS/BODMAS) to calculate the result:

Step 1: First, we evaluate any operations inside parentheses or brackets. There are none in this expression.

Step 2: Next, we calculate any exponents or roots. In this case, we have √2, which means the square root of 2. Taking the square root of 2 is approximately 1.414.

2+2×2÷2-1.414+22-10+7-5×10

Step 3: Moving from left to right, we perform multiplication and division operations.

2 + (2 × 2 ÷ 2) - 1.414 + 22 - 10 + 7 - (5 × 10) 2 + (4 ÷ 2) - 1.414 + 22 - 10 + 7 - 50

Step 4: Perform the addition and subtraction operations from left to right.

2 + (4 ÷ 2) - 1.414 + 22 - 10 + 7 - 50 2 + 2 - 1.414 + 22 - 10 + 7 - 50 4 - 1.414 + 22 - 10 + 7 - 50 2.586 + 22 - 10 + 7 - 50 24.586 - 10 + 7 - 50 14.586 + 7 - 50 21.586 - 50 -28.414

So, the value of the expression 2+2×2÷2-√2+22-10+7-5×10 is -28.414.
