**How do you multiply numbers with exponents? **

An exponent refers to the number of times a number is multiplied by itself. Exponents are also called Powers or Indices. Exponential notation is an easier way to write a number as a product of many factors.

The number being multiplied is the base and the exponent tells you how many times the base is multiplied.

**What are exponent examples? **

**6 ^{2} Â Â Â = Â Â Â 6 Ã— 6**

**6**

^{3}Â Â Â = Â Â Â 6 Ã— 6 Ã— 6**6**

^{4}Â Â Â = Â Â Â 6 Ã— 6 Ã— 6 Ã— 6**6**

^{5}Â Â Â = Â Â Â 6 Ã— 6 Ã— 6 Ã— 6 Ã— 6### What if the Exponent is 1, or 0?

If the exponent is 1, then you just have the number itself (example 4^{1} = 4)

Any nonzero number raised to the power of zero equals 1 (example 4.84^{0} = 1)

But what about 00? It could be either 1 or 0, and so people say it is “indeterminate”.

A number with an exponent of two is known as a square of a number.

Â is read as sevenÂ squared

A number with an exponent of three is known as a cube of a number.

Â is read as nine cubed
