SECTION 3. WHAT IS AN EXPONENT?
An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means:
23 is not the same as 2 x 3 = 6.
Remember that a number raised to the power of 1 is itself. For example,
There are some special cases:
You can have a variable to a given power, such as a3, which would mean a x a x a. You can also have a number to a variable power, such as 2m, which would mean 2 multiplied by itself m times. We will deal with that in a little while.
