Rewriting a number into scientific notation with a positive power

The video tutorial explains how to write numbers in scientific notation. It covers the importance of the 'a' component, which must be between 1 and 10, and demonstrates how to place the decimal point correctly. The tutorial also guides viewers on adjusting the decimal point to convert a number into scientific notation, emphasizing the need to count the spaces moved to determine the exponent.

What is the range for the coefficient 'a' in scientific notation?

• 100 to 1000

• 10 to 100

• 0 to 1

• 1 to 10

Why is it important to ensure 'a' is between 1 and 10 in scientific notation?

• To avoid using decimals

• To make the number larger

• To standardize the format

• To simplify calculations

Where should the decimal point be placed in the number 497 to convert it to scientific notation?

• Before 4

• Between 4 and 9

• Between 9 and 7

• After 7

If you move the decimal point 5 places to the right, what will be the exponent in scientific notation?

• -5

• 10

• 0

• 5

In scientific notation, what does the exponent represent?

• The value of 'a'

• The position of the decimal point

• The size of the number

• The number of decimal places moved
