**Index Laws**

**Index Laws**

### Numbers that have the** same base number** but **different indices** when **multiplied**, you just **add** the indices.

### Numbers that have the **same base number** but **different indices** when **divided**, you just **subtract** the indices.

**Zero Index Law**

**Zero Index Law**

### Any number with an index of 0 **always equals 1**.
