Sqrt

Function: sqrt (<x>) The square root of <x>. It is represented internally by <x>^(1/2). See also rootscontract.

m: 4;
e0: ((m+1)*x+(m-1)*y)/(2*m);
e1: ((m-1)*x+(m+1)*y)/(2*m);
fullratsimp(subst(e0, y, e1));
 solve((a-r)*(d-r)-b*c,r);
a0: 0;
a1: 1;
a: 49/64;
b: 15/64;
c: 3/8;
d: 5/8;
sqrt(a^2+d^2-2*a*d+4*b*c);
a1*b/sqrt(a^2+d^2-2*a*d+4*b*c);

radexpand if true will cause nth roots of factors of a product which are powers of n to be pulled outside of the radical, e.g. sqrt(16*x^2) will become 4*x only if radexpand is true.

There are also some inexact matches for sqrt. Try ?? sqrt to see them.
