How to fill out reteaching 4-9 scientific notation

How to fill out reteaching 4-9 scientific notation:

1. Start by reviewing the basic principles of scientific notation. Scientific notation is a way to express numbers that are either very large or very small in a more compact and manageable form. It uses a decimal number between 1 and 10, multiplied by a power of 10.
2. Identify the number you need to convert into scientific notation. This could be a number that is either extremely large or extremely small.
3. Determine the power of 10 that you need to multiply the decimal number by. If the original number is large, the power of 10 will be positive. If the number is small, the power of 10 will be negative.
4. Write the decimal number in scientific notation form by placing a decimal point after the first non-zero digit. Then, multiply this number by 10 raised to the power determined in the previous step. For example, if you have the number 500,000 and the power of 10 is 5, the scientific notation form would be 5 x 10^5.
5. Simplify the scientific notation if possible. Sometimes, the decimal number can be expressed as a whole number, without any decimal places. In this case, remove the decimal point and adjust the power of 10 accordingly. For example, if the original number is 0.000075 and the power of 10 is -5, the simplified scientific notation form would be 75 x 10^-7.
