hi
someone please tell me in a very layman's language about following
problem
1.why anything raised to the power of zero i equal to one (x^0=1)
2.How can i resolve x^1/2 without going through root. i mean resolve it
through only the power manipulation.
3.Easiest way of getting to the square root of any figure (no use of
calculator or any other computerized help).
thanx in advance

.
