Square Root Equations

Let's go through each equation and determine if the given square root equations are correct or not.

1. √100 = -10 - This equation is incorrect. The square root of 100 is 10, not -10.

2. √25 = 5,1 - This equation is incorrect. The square root of 25 is 5, not 5.1.

3. √49 = 7 - This equation is correct. The square root of 49 is indeed 7.

4. √(-3)² = -3 - This equation is incorrect. The square root of a squared number is always positive. Therefore, the square root of (-3)² is 3, not -3.

To summarize: - The correct equations are: - √49 = 7 - The incorrect equations are: - √100 = -10 - √25 = 5.1 - √(-3)² = -3

I hope this clarifies the correct square root equations for you. If you have any further questions, feel free to ask!
