**Laws of exponent pcs exam.**

In the exponent notation, **a ⁿ** we say that in mathematical word **(read as base a**** to**** the n power)**. We call ‘a’ is the base and ;n; is the exponent of power to which the base is raised.

From this definition, recall that we have the following law of exponent.

**If a, b ∈ R and m, n are positive integers, then**

**(1)Law of addition exponent**

when base are same and exponent are different, only exponent add

**Example:**

Proper and improper subset example

**(2) Base are different and power are same**

when base are different and power are same, then law of exponent is the form.

EXAMPLE: pcs exam

**(3)Different base power exponent:**

**(4) Rational law of exponent:**

we have two rational number a, b and whole power n then the law of exponent is the form
