Question: how do u type squared?
Answer: Try holding down one of the Alt keys and typing 0178 on the NumPad (with NumLock ON) then releasing the Alt key for the ² (i.e. squared) symbol. Cubed (e.g. ³) is Alt+0179 and there are a host of others (both supersript and subscript) within the Unicode character set starting around the U+2070 area.
