Have you ever heard of powers? Do you know what they are and what they’re for?

In this week’s post, we are going to discover *what a power is and why we use them.*

**Powers are an abbreviated way of writing a number that’s formed by multiplying a number by itself various times.** They are very useful for simplifying multiplications that repeat a certain number.

Powers consist of a **base** and an **exponent**. The base is the number that is multiplied various times and the exponent is the number of times that the base is multiplied.

What number is multiplied?** THE BASE.**

How many times is the number multiplied? **THE EXPONENT.**

Powers are written as such: the base number is written normally and the power number is written on the upper-right-hand side in a smaller text.

##### Powers example:

### 5 x 5 x 5 x 5 x 5 x 5 x 5

What number is being multiplied?** 5 ****→ BASE**

How many times is the number being multiplied? **7 ****→ EXPONENT**

The number would be expressed as: Let’s look at another example.

### 3 x 3 x 3 x 3

What number is being multiplied? 3 → BASE

How many times is the number being multiplied? 4 → EXPONENT

3 x 3 x 3 x 3 = **3 ^{4}**
