Whenever there is a negative under the radical sign, it comes out from underneath as i since the problem will contain a square root of -1.

The location of the Personal Macro Workbook is a little confusing, because older versions of Excel stored it in an XLSTART folder buried inside the Program Files folder. Even though you canât write any files to it, Excel 2007 and Excel 2010 also have XLSTART folders inside the Program Files directory.
Close any open workbooks and then exit Excel. A message appears that prompts you to save the changes that you made to the Personal Macro Workbook. Click Save to save the personal workbook. The next time you open Excel, the macro you created is available. To see it: Click Developer Macros. Our example macro is called PERSONAL!.BoldMe. If you donât see the macro, in the Macros in box, click PERSONAL.XLSB. To run the macro, see Run a macro.
