Product of Powers Rule

## Study Notes

## Exponents: Understanding Power Rules

Exponents, also known as indices or raised numbers, allow us to represent repeated multiplications more concisely. They play a crucial role in algebraic manipulations because they follow specific rules we can apply when dealing with expressions containing exponentials. Let's dive into three key properties of exponents: product of powers, power of a power, and power of a product.

### Product of Powers Property

This rule states that if you have two identical bases raised to separate powers, multiplying those expressions equals raising their sum as the exponent of the common base. For example:

(a^m \times a^n = a^{m + n})

Take (a^2 \times a^3):

((a^2)(a^3)=a^{(2+3)}=a^5)

In simple terms, this means that whenever you see multiple instances where the same base is raised to different exponents, combine them by adding the exponents and keeping only one set of parentheses around the single base term.

### Power of a Power Property

According to this rule, raising a number to the power of another number raised to its own exponent results in the original number being raised to the second exponent, squaring the first exponent:

((a^m)^n = a^{mn})

For instance:

((x^2)^3 = x^{2 \times 3} = x^6)

Imagine standing on a staircase made up of many steps; each time we step onto the staircase ((a^m)), it counts as one unit (step), so if we climb up the staircase twice ((m = 2)) and turn around to do it again ((n = 3)), we will reach the top after climbing up a total of (2 \times 3 = 6) stairs.

### Power of a Product Property

The third property tells us how to evaluate an expression like the product of two or more variables raised to the same exponent:

((ab)^n = a^n b^n)

Here, (a) and (b) must be evaluated independently of each other before taking (n)-th roots or applying any other operations involving (n). This principle allows us to simplify complex products by separating the individual terms inside the parentheses and raising each separately to the given exponent.

To help remember these properties, think of them visually as going from left to right when reading:

Product Rule: Left → Add → Right Power of a Power Rule: Inside Out Power of a Product Rule: Separate Terms → Raise Each Term Individually to the Same Exponent

By understanding and utilizing these conventions, solving equations and representing information using exponential notation becomes more manageable.
