** Problem 1** Rewrite 1784.5 x 10^{8} with proper engineering notation | |

**Procedure** | |

- Increase the exponent by 1, from 8 to 9.
This makes the exponent a multiple of 3. | 1784.5 x 10^{8} = ? x 10^{9} |

- Move the decimal point in the coefficient one place to the left.
This is absolutely necessary to avoid changing the actual value of the number. | 1784.5 ® 178.45 |

- Assemble the results
| 1784.5 x 10^{8} = 178.45 x 10^{9} |

**Solution** 1784.5 x 10^{8} = 178.45 x 10^{9} | |
