Laws of Indices
There are certain laws that are to be followed while carrying out operations with Indices / Exponents.
The laws
- Multiplication - When the base is same in both the terms, we dd the exponent and keep the base same - 26 x 24= 210
- General rule - am x an = am+n
2. Division - When the base is same in both the terms, we subtract the exponent and keep the base same - 26 ÷
24= 32
- General rule - am ÷ an = am-n
3. Brackets - When the whole term is raised to an exponent, we multiply both the exponents and keep the base - (26)2= 26 x 26= 212
- General rule - (am)n = am x n
4. Index of 0 - When any letter or number raised to 0, the answer will be 1. - 30=1
- General rule - a0 = 1
5. Negative Exponent
- When the base is raised to a negative exponent, the term becomes a fraction and then we have to make the negative exponents positive and do it with the fraction. -
