Numerical Evaluation of Sqrt[]


Folks,

I'm a new user of Mathematica and am unable to get a full numerical
evaluation of the Sqrt function in one case.  Following are the
input and output lines of the case giving me trouble.

In[]:=	a=2;
	b=2;
	c=2;
	d=2;
	e=2;
	f=2;
	g=Sqrt[(a+b)^2 + (c+d)^2 + (e+f)^2]

Out[]=	Sqrt[32. + 16. ]

I've tried appending //N and inclosing the function in N[], but the
result is the same.  I'd be grateful for any pointers,

Please respond directly to me at <lindell at arl.mil>.

Thanks,
Dennis
