Answer 1

Не знаю, так или не так

Answer 2

Let's break down the expression step by step:

1. Start with the expression: -4.75 + 3.25 + √6(2 - √6) / (-2/3)

2. Calculate the value inside the square root and simplify the expression inside the parentheses: 2 - √6

3. Now, let's simplify further: -4.75 + 3.25 + √6(2 - √6) / (-2/3)

4. Subtract 4.75 from 3.25: -1.5 + √6(2 - √6) / (-2/3)

5. To simplify the expression involving the square root, you can multiply both the numerator and denominator by 3 to get rid of the fraction in the denominator: -1.5 * (3/3) + √6(2 - √6) * (3/3) / (-2/3)

6. Simplify: -4.5 + 3√6(2 - √6) / (-2/3)

7. Now, let's deal with the negative sign in front of the fraction. Multiply both the numerator and denominator by -1 to get rid of the negative sign: (-4.5 * -1) + (3√6(2 - √6) * -1) / (-2/3)

8. Simplify further: 4.5 - 3√6(2 - √6) / (2/3)

9. Now, multiply the numerator and denominator by 3 to get rid of the fraction in the denominator: (4.5 * 3) - (3√6(2 - √6) * 3) / 2

10. Simplify: 13.5 - 9√6(2 - √6) / 2

11. Finally, simplify the expression in the parentheses: 13.5 - (9√6 * 2 - 9√6 * √6) / 2

12. Continue to simplify: 13.5 - (18√6 - 54) / 2

13. Now, simplify further by dividing each term by 2: 13.5 - (9√6 - 27)

14. Subtract (9√6 - 27) from 13.5: 13.5 - 9√6 + 27

15. Combine like terms: 40.5 - 9√6

So, the simplified value of the expression is approximately 13.5 - 9√6.
