The exponent that a number claims how countless times to usage the number in a multiplication.

You are watching: What is three to the third power

In 82 the "2" states to use 8 double in a multiplication,so 82 = 8 × 8 = 64

In words: 82 can be dubbed "8 to the power 2" or "8 come the 2nd power", or merely "8 squared"

Exponents are also called strength or Indices.

Some more examples:

### Example: 53 = 5 × 5 × 5 = 125

In words: 53 could be called "5 to the third power", "5 come the strength 3" or merely "5 cubed"

### Example: 24 = 2 × 2 × 2 × 2 = 16

In words: 24 might be dubbed "2 come the 4th power" or "2 come the power 4" or just "2 come the 4th"

So in general:

 an speak you to main point a by itself,so there space n that those a"s:

## Another means of creating It

Sometimes human being use the ^ prize (above the 6 on your keyboard), together it is basic to type.

## Negative Exponents

Negative? What can be the opposite of multiplying? Dividing!

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

## Negative? upper and lower reversal the Positive!

 That last example showed one easier way to handle an unfavorable exponents: calculate the positive exponent (an)

More Examples:

negative Exponent reciprocal 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 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 so world say that is "indeterminate".

## It All renders Sense

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

Example: strength of 5
