Learn how to write a decimal as a number in scientific notation

The video tutorial explains how to identify the correct placement of a decimal point in numbers and introduces the concept of scientific notation. It covers the criteria for determining decimal placement, such as ensuring the number is between 1 and 10. The tutorial then demonstrates how to convert a number into scientific notation by moving the decimal point and calculating the power of ten. The process is illustrated with an example, and viewers are encouraged to verify their work.

What is the first step in identifying where the decimal point should be placed?

• Determine the number's magnitude

• Check if the number is negative

• Identify the number of digits

• Look for the largest digit

What is the range within which the decimal point should be placed?

• Between 0 and 10

• Between 0 and 1

• Between 1 and 10
