The exponent of a number states how plenty of times to use the number in a multiplication.

You are watching: 6 to the power of 5 In 82 the "2" states to use 8 twice in a multiplication,so 82 = 8 × 8 = 64

In words: 82 might be referred to as "8 come the strength 2" or "8 come the second power", or just "8 squared"

Exponents are also called strength or Indices.

Some more examples:

### Example: 53 = 5 × 5 × 5 = 125

In words: 53 can be referred to as "5 to the 3rd power", "5 to the strength 3" or just "5 cubed"

### Example: 24 = 2 × 2 × 2 × 2 = 16

In words: 24 could be referred to as "2 to the 4th power" or "2 come the strength 4" or simply "2 come the 4th"

So in general:

 an tells you to multiply a by itself,so there are n of those a"s: ## Another means of creating It

Sometimes world use the ^ price (above the 6 on your keyboard), as it is straightforward to type.

## Negative Exponents

Negative? What could be the contrary of multiplying? Dividing!

So we division by the number each time, i beg your pardon is the exact same as multiply by 1number

## Negative? upper and lower reversal the Positive! That last example showed an easier way to handle negative exponents: calculate the positive exponent (an)

More Examples:

an unfavorable Exponent mutual ofPositive Exponent price
4-2 = 1 / 42 = 1/16 = 0.0625
10-3 = 1 / 103 = 1/1,000 = 0.001
(-2)-3 = 1 / (-2)3 = 1/(-8) = -0.125

## What if the Exponent is 1, or 0?

 1 If the exponent is 1, climate you just have actually the number chin (example 91 = 9) 0 If the exponent is 0, then you get 1 (example 90 = 1) But what about 00 ? It could be one of two people 1 or 0, and also so world say it is "indeterminate".

## It All renders Sense

If girlfriend look at that table, you will check out that positive, zero ornegative exponents space really part of the exact same (fairly simple) pattern:

Example: powers of 5
