Exponents and Scientific Notation

Introduction

In this lesson, we will learn how to use exponents and scientific notation. It is called scientific notation because scientists often work with large and small numbers and so they use exponents to make it easier for them to calculate numbers.

Exponents and Scientific Notation

Let's say that we have the number 126. In order to convert this into scientific notation, we need to first convert the number 126 into a decimal. If I do 1.26, it isn't the same numbers however
 (1.26) (100) does equal 126.
So, the scientific notation for 126 is 1.26 x 10 to the power of 2!

{The reason I wrote 10 to the power of 2 is because 10 X 10 equals 100}
