|Exponents are a shorthand way to show how many times a number, called the base, is multiplied to itself. A number with an exponent is said to be "raised to the power" of that exponent. |
2 x 2 x 2 x 2 = 2 to the power of 4
2 4 = 16
2 is called the Base
4 is called the power, exponent or index
|101||ten to the first power||10|
|32||three to the second power or three squared||3 x 3|
|23||two to the third power or two cubed||2 x 2 x 2|
|54||five to the fifth power||5 x 5 x 5 x 5 x 5|
|xn||x to the nth power||x.x.x.x.x..........n times|
- Any number raised to the zero power (except 0) equals 1.
Example: 30 = 1
- Any number raised to the power of one equals itself.
Example: 41 = 4
- To find 10 to the power of any number, simply add the same number of zeros after 1.
Example: 103 = 1000
