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.

Example:Two raised to the power of three = 2

^{3}= 2 × 2 × 2 = 8

Any number raised to the power of one equals itself, for example:

15

^{1}= 15

Any number (except 0) raised to the zero power equals 1, for example:

322

^{0}= 1

A **negative
exponent** means that the base is changed to its reciprocal and then raised to
the power of the positive exponent, for example:

The following video show more examples of negative exponents:5

^{-3}=

5

^{4}x 5^{-3}= 5^{4-3}= 5

A **fractional exponent** in the form of means to take the nth root of the base, for example:

is the square root of 4.

The following video show more examples of fractional exponents:

If two numbers with exponents have the same base, you can multiply them by adding the exponents, for example:

45

^{10}× 45^{31}= 45^{41}

When you have a **power of a power**, you multiply the exponents, for example:
