An oversight
Try
(sqrt(x+h)-sqrt(x))/h;
% / (sqrt(x+h)-sqrt(x));
radcan(%);
-> 1/(h*(sqrt(x+h)-sqrt(x)))

Why do you want to make the numerator 1?
Anyway an answer is
(sqrt(x+h)-sqrt(x))/h;
% / (sqrt(x+h)-sqrt(x));
-> 1/(h*(sqrt(x+h)-sqrt(x)))

Hi all, more questions from a newbie reviewing calculus:
If F(x)=sqrt(x), then
F(x+h) =sqrt(x+h) and
(F(x+h) ?F(x))/h = (sqrt(x+h) ?sqrt(x))/h.
To set the numerator to 1 we multiply thru by
sqrt(x+h) + sqrt(x)/((sqrt(x+h) +sqrt(x))
this yields
1/(sqrt(x+h) + sqrt(x)).
My question is this. How do I ask Maxima to set the numerator to a specific value, in this case 1?
