You may find Math Stackexchange helpful. Dr. Math also likely has something in their archives.

However, this forum is specifically for asking how to do things with Sage mathematics software. We can compute radicals of ideals, which could conceivably help you gain intuition:

sage: P.<x,y,z> = QQ[]
sage: I = Ideal(x+y+z-3,x^2+y^2+z^2-5,x^3+y^3+z^3-7)
