To add indices, you simply add the coefficients of the same base while keeping the base unchanged. For example, if you have ( a^m ) and ( a^n ), you can write their sum as ( a^m + a^n = a^m(1 + a^{n-m}) ) if ( m \neq n ). If the indices are the same, you can factor them out, resulting in ( k \cdot a^m ) where ( k ) is the sum of the coefficients.
