Example: 5×5×5×5 = 54 (5 to the Law of Indices. To manipulate expressions, we can consider using the Law of Indices. These laws only apply to expressions with the same base, for example, 3 4 and 3 2 can be manipulated using the Law of Indices, but we cannot use the Law of Indices to manipulate the expressions 3 5 and 5 7 as their base differs (their bases are 3 and 5, respectively).
