Square Root Function

Usage

Square[x] displays as square x.

Root[{f, c}] represents the exact root of the general equation f[x]==0 near x=c.
Root[{{f1, ..., fn}, {c1, ..., cn}}, j] represents the j ^th coordinate of the exact root of the system of equations {f1[x1, ..., xn]==0, ..., fn[x1, ..., xn]==0} near {x1, ..., xn}={c1, ..., cn}.
Root[f, k] represents the exact k ^th root of the polynomial equation f[x]==0. 
Root[{f1, f2, ...}, {k1, k2, ...}] represents the last coordinate of the exact vector {a1, a2, ...} such that ai is the ki ^th root of the polynomial equation fi[a1, ..., a i-1, x]==0.
