In this video, we are going to look at how to simplify numbers raised to positive exponents. After you finish this lesson, view all of our Algebra 1 lessons and practice problems.
For example:
To simplify the following:
we have to multiply the 2 by itself, 4 times which would simplify to:

Examples of Positive Exponents
Example 1
We have to multiply four times.
Example 2
We have to multiply two times.
Video-Lesson Transcript
This is a quick lesson on positive exponents.
Let’s look at an example.
is known as the base and the
is the exponent
This means that we’re going to multiply the base by itself by the number of the exponent.
So
Our final answer is .
is
multiplied
times.
is not the same as
.
What if we have ?
This means we’re going to multiply
times.
If we have this is
multiplied
times.
So we have to multiply the base by itself. The number of times you do it is what the exponent stands for.
If you see a term or variable raised to an exponent such as .
This only means that we have multiplied by itself
times.
Just to review, we have the base and the small number at the top is the exponent.
