**The exponent of a number says how many times to use that number in a multiplication. It is written as a small number to the right and above the base number. In this example: 82 = 8 × 8 = 64. (The exponent "2" says to use the 8 two times in a multiplication.) X raised to Y means that x is multiplied by itself y times.**

Rule: - a n = a × a × ... × a

Contents: - "n" times and "a" is the base and n is the exponent.

Laws of Exponents:-

- When multiplying like bases, keep the base the same and add the exponents.

- When raising a base with power to another power, keep the base the same and multiply the exponents.

- When dividing like bases, keep the base the same and subtract the denominator exponent from the numerator exponent.

- When there are two or more exponents and only one base, multiply the exponents.
