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
