Hi All,
I should point out that I use Mathematica 4.0 infrequently, thus I may be
missing the obvious. My problem is as follows:
In the following I use the square root sign from the palette for SQRT
Expand[(44+9*SQRT(23))^2] yields
3799 + 792*SQRT(23)
I now wish to take the square root of 3799 + 792*SQRT(23) to return to my
original expression. However
Expand[SQRT(3799 + 792*SQRT(23))] merely yields
[SQRT(3799 + 792*SQRT(23))]
What is the proper command to make SQRT(3799 + 792*SQRT(23)) yield
44+9*SQRT(23)
Best wishes, Jim
