Introduction to Scientific Notation: Writing and Understanding Large Numbers

This video tutorial introduces scientific notation, a method for writing large numbers using a number between 1 and 10 multiplied by a power of 10. It reviews multiplying by powers of 10 and explains how to convert large numbers into scientific notation and vice versa. The tutorial also clarifies the calculator shorthand 'E' for scientific notation.

What is a common mistake when multiplying by powers of 10?

• Counting decimal places in the wrong direction

• Moving the decimal point to the left

• Forgetting to add zeros

• Multiplying by the wrong power of 10

Which of the following is a correct representation of a number in scientific notation?

• 6.97 x 10^9

• 0.5 x 10^3

• 100 x 10^1

• 15 x 10^2

How do you determine the power of 10 when converting a large number to scientific notation?

• Count the number of digits before the decimal point

• Count the number of digits after the decimal point

• Count the number of places the decimal point is moved

• Count the number of zeros in the number

What does the 'E' notation on a calculator represent?

• A large number

• An error in calculation

• Exponentiation

• Scientific notation

If a number is written as 5.23 x 10^4 in scientific notation, what is its value in regular notation?

• 523,000

• 52,300

• 5,230

• 523
