How to write out a number using scientific notation

The video tutorial explains how to rewrite numbers in scientific notation, emphasizing the importance of moving the decimal point correctly based on whether the exponent is positive or negative. It highlights the need for the first number to be between 1 and 10 and stresses the importance of checking your work to ensure accuracy. An example problem is solved to demonstrate the process.

What should you do with the decimal point if the exponent in scientific notation is positive?

• Move it to the left

• Move it to the right

• Keep it in the same place

• Remove it completely

Why is it important for the first number in scientific notation to be between 1 and 10?

• To make calculations easier

• To simplify the number

• To ensure the notation is standardized

• To avoid negative exponents

What is the range for the first number in scientific notation?

• Between 0 and 1

• Between 10 and 100

• Between 0 and 10

• Between 1 and 10

If you move the decimal point six places to the left, what power of ten should you use?

• 10^-6

• 10^6

• 10^-5

• 10^5

In the example given, what is the correct scientific notation for 10.8?

• 10.8 x 10^6

• 1.08 x 10^6

• 1.08 x 10^-6

• 10.8 x 10^-6
