Question

√2500=√0,001=(2√6)²/36=(√85-1)²=√20+√5=√4+2√3-√4-2√3=√3×27=√√625=​

Answer 1

√2500=50

√0,001=√10/100 (в виде дроби)

(2√6)²/36=2/3=0,6

(√85-1)²=86-2√85=68

√20+√5=6√5 3√5*(3√2+1)*(3√4-3√2+1)=7

√4+2√3-√4-2√3=0

√3×27=27√3=47

√√625=5

Answer 2

Let's break down the given equation step by step:

1. √2500 = √0.001

The square root of 2500 is 50, not 0.001. Therefore, this step is incorrect.

2. (2√6)²/36

The square of 2√6 is 24, and when divided by 36, it simplifies to 2/3. Therefore, this step is correct.

3. (√85-1)²

The square of (√85-1) is (√85-1) * (√85-1) = 85 - 2√85 + 1 = 86 - 2√85. Therefore, this step is incorrect.

4. √20 + √5

This expression cannot be simplified further. Therefore, this step is correct.

5. √4 + 2√3 - √4 - 2√3

The terms cancel each other out, resulting in 0. Therefore, this step is correct.

6. √3 × 27

The square root of 3 multiplied by 27 is 27√3. Therefore, this step is correct.

7. √√625

The square root of 625 is 25, and the square root of 25 is 5. Therefore, this step is correct.

In summary, some of the steps in the given equation are incorrect, and the correct value cannot be determined from the given steps.
