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

You are watching: What is 10 to the -2 power

In **82** the "2" says to usage 8 twice in a multiplication,**so 82 = 8 × 8 = 64**

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

Exponents are likewise called strength or Indices.

Some more examples:

### Example: **53 = 5 × 5 × 5 = 125**

In words: 53 could be dubbed "5 to the third power", "5 to the strength 3" or merely "5 cubed" ### Example: **24 = 2 × 2 × 2 × 2 = 16**

In words: 24 can be referred to as "2 come the fourth power" or "2 to the power 4" or simply "2 to the 4th" So** in general**:

an speak you to multiply a by itself,so there space n of those a"s: |

## Another method of creating It

Sometimes world use the **^** price (above the 6 on her keyboard), together it is straightforward to type.

## Negative Exponents

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

So we divide by the number every time, i beg your pardon is the same as multiply by *1***number**

## Negative? upper and lower reversal the Positive!

That last example showed one easier way to handle an adverse exponents: calculation the positive exponent (an) |

More Examples:

an unfavorable Exponent mutual of

**Positive 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 itself (example 91 = 9) | |

0 | If the exponent is 0, then you gain 1 (example 90 = 1) | |

But what around 00 ? It can be one of two people 1 or 0, and also so human being say that is "indeterminate". |

## It All makes Sense

If friend look at the table, girlfriend will view that positive, zero ornegative exponents space really component of the same (fairly simple) pattern:

Example: powers of 5
