How to square root in C# (help needed)

Question

So my older brother challenged me to do the quadratic function in C# and I can't seem to find a way to do the square root of a number.. Help?
Ps: so far i've learned all the way to classes and objects, if the sqrt of an int is still beyond my knowledge, let me know, fellow human.
