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. When simplifying these radical numbers in terms of i, follow the usual rules for simplifying radicals and treat the i with the rules for working with a variable. Examples:
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.
1. I created a few macros in Excel 2007 and I saved them in the personal macro workbook. Since then, I've deleted the macros. Note: You have to unhide the workbook, delete the macro and then hide it again to accomplish this.:\Program Files\Microsoft Office\Office\XLStart. If you have deleted all the macros from the personal macro workbook, you can delete the file PERSONAL.XLSB. This should cause Excel to stop doing what you described.
