Definition of Indices:

Indices or index (singular) deals with numbers raised to some power

e.g. a5 is read as “a raised to the power 5”. Here 5 is called the index, power, or quotient while a is called the base.

Indices can also be referred to as exponents.

Laws of Indices:

1. \( \scriptsize X^a \times X^b = X^{a + b} \)

2. \( \scriptsize X^a \div X^b \: or \: \normalsize \frac{X^a}{X^b} \scriptsize = X^{a – b} \)

3. \( \scriptsize X^0 = 1 \)
