OBJECTIVE (Students will be able to…):
Use various operations to simplify expressions in Scientific Notation.
Multiplying Numbers in Scientific Notation
|NOTES: |Multiplying two numbers in Scientific Notation: |
| |Multiply both coefficients by one another. |
| |Multiply the exponent terms using the algorithm for multiplying exponents. |
| |If the result of the simplification is not in scientific notation, correct it, so it is in scientific notation. |
| | |
| |Multiplying a whole number by Scientific Notation: |
| |Multiply the whole number by the coefficient. |
| |If the result of the simplification is not in scientific notation, correct it, so it is in scientific notation. |
|EXAMPLES:|Simplify the following into Scientific Notation |
| |Ex 1: [pic] Ex. 2: [pic] |

Dividing Numbers in Scientific Notation
|NOTES: |Dividing two numbers in Scientific Notation: |
| |Divide both coefficients by one another. |
| |Divide the exponent terms using the algorithm for dividing exponents. |
| |If the result of the simplification is not in scientific notation, correct it, so it is in scientific notation. |

Powers of Powers with Scientific Notation:
|NOTES: |To simplify Powers of Powers with Scientific Notation: |
| |Take the exponent and apply it to the coefficient number, then simplify. |
| |Take the exponent and create a power of power with the existing power of ten. |
| |If the result of the simplification is not in scientific notation, correct it, so it is in scientific notation. |
|EXAMPLES:|Simplify each expression. Write each answer in Scientific Notation: |
| |Ex 1. [pic] Ex 2. [pic] |
