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

You are watching: -4 to the 4th power

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

In words: 82 can be dubbed "8 come the power 2" or "8 come the second power", or simply "8 squared"

Exponents are additionally called powers or Indices.

Some much more examples:

### Example: **53 = 5 × 5 × 5 = 125**

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

In words: 24 might be called "2 come the 4th power" or "2 to the strength 4" or just "2 to the 4th" So** in general**:

an tells you to main point a by itself,so there room n the those a"s: |

## Another method of writing It

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

## Negative Exponents

Negative? What could be opposing of multiplying? Dividing!

So we divide by the number every time, which is the very same as multiplying by *1***number**

## Negative? flip the Positive!

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

More Examples:

negative Exponent reciprocal of

**Positive Exponent answer**

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, then you just have actually the number chin (example 91 = 9) | |

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

But what around 00 ? It might be either 1 or 0, and also so world say the is "indeterminate". |

## It All makes Sense

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

Example: powers of 5
