I was trying to resolve some mathematicals problems about the limits and the functions, but I still don't understand something at all, and I want to know if you can help me !
The problem is that I never understood the trick with 0 and the square root function :
-We know that we can't divide any number by 0, the result won't make any sense.
-We know that a real number divided by his square root is equal to his square root.
For example : 9/3=3, 3 is the square root of 9
But, what is the solution if the real number is 0 ? How do we deal with 0/0=0 ? Is the square root of 0 possible ?
