Answer 1

Ответ:

Объяснение:

-2,(3)=х

Тогда 10х = 10*-2,(3) =-27,(3)

10х -х =9х     -23,(3) –(- 2,(3) =-23,(3)+2,(3) =-21

9х=-21  // 9

х= -21/9=-7/3

-7/3=-2,(3)

Answer 2

It seems like you've provided a list of numbers and a word "ироционал" which appears to be a transliteration of the word "irrational" in Cyrillic script. Let me clarify what each part means:

1. -2: This is a negative integer, specifically the number negative two.

2. (3): This appears to be a positive integer, specifically the number three. The parentheses around it might indicate some significance or context.

3. ироционал: This word translates to "irrational" in English. In mathematics, an irrational number is a real number that cannot be expressed as a simple fraction or ratio of two integers. Common examples of irrational numbers include the square root of 2 (√2), pi (π), and Euler's number (e).

If you have any specific questions or need further information about these numbers or the concept of irrational numbers, please feel free to ask.
