Understanding Scientific Notation Concepts

The video tutorial explains how to rewrite numbers using scientific notation. It begins by introducing the concept and criteria for scientific notation, such as the absolute value being between 1 and 10. The tutorial then demonstrates converting a large number by moving the decimal point and using a positive exponent. Finally, it covers converting a small number by using a negative exponent, ensuring the number remains between 1 and 10.

What is the first step in rewriting a number using scientific notation?

• Divide the number by 10

• Multiply the number by 100

• Move the decimal point to create a number between 1 and 10

• Add zeros to the number

When converting a number to scientific notation, what should the absolute value of the number be?

• Equal to 0

• Greater than 10

• Less than 1

• Between 1 and 10

How do you determine the exponent when using scientific notation with a positive exponent?

• Count the number of zeros

• Count the number of decimal places moved

• Divide by 10

• Multiply by 10

What is the exponent sign when converting a small number to scientific notation?

• Negative

• Positive

• Zero

• Undefined

In scientific notation, what is the value of the exponent if the decimal is moved four places to the left?

• -10

• 10

• -4

• 4
