How To Write Indices In Root Form
Indices (the plural of index) are the lazy mathematician’s way of abbreviating operations such as multiplication and division. You do not have to use this technique if you have the time to do otherwise. For example, the lazy mathematician might write x6, whereas you could write x ? x ? x ? x ? x ? x. Why use indices at all? Because doing so will save you time and effort in more dif?
