whats the difference between the square root of 25 the square root of negative 25 and the square root of plus minus 25?
Dmitrij [34]

The answer is 8 because 8 x 8 = 64 If you see these kinds of problem what is the square root of 25, 64, 36... means 5 x 5 = 25, 8 x 8 = 64, 6 x 6 = 36 If you see square root of 48. It would come out to be a decimal number.

Use the distance formula to find the length of the line with endpoints at (1,3) and (3,1)?
gulaghasi [49]
Let's plug the coordinate point values into the equation: 
\sqrt{(3-1)^{2} +(1-3)^{2} }
(1,3) is x₁ and (3,1) is x₂
Begin to simplify within the parenthesis: 
\sqrt{2^{2}+(-2)^{2}  }
Square the two numbers: 
\sqrt{4 + 4} 
Add the two to get: 
\sqrt{8} 
Since 8 is not a square number, this is as far as we can simplify this. Hope this helps!
