Comparing Numbers in Scientific Notation

The video tutorial explains how to compare numbers in scientific notation by examining exponents and coefficients. It begins with an introduction to scientific notation and the importance of exponents. The tutorial then demonstrates how to compare numbers by their exponents and, if necessary, by their coefficients when exponents are equal. It also covers how to calculate how many times larger one number is than another using division and multiplication of coefficients and powers of 10. The video concludes with practical examples to reinforce the concepts.

What is the first step in comparing numbers written in scientific notation?

• Multiply the numbers

• Convert to standard form

• Compare the exponents of the powers of 10

• Compare the coefficients

If two numbers in scientific notation have the same exponent, what should you compare next?

• The coefficients

• The base of the powers of 10

• The standard form of the numbers

• The sum of the exponents

Which number is larger: 5.2 × 10^5 or 9.4 × 10^4?

• They are equal

• 9.4 × 10^4

• Cannot be determined

• 5.2 × 10^5

What is the standard form of 5.2 × 10^5?

• 5,200

When comparing 8.7 × 10^9 and 8.8 × 10^9, which number is larger?

• They are equal

• Cannot be determined

• 8.8 × 10^9

• 8.7 × 10^9

If the exponents are the same, which part of the numbers in scientific notation do you compare?

• The base of the powers of 10

• The coefficients

• The sum of the exponents

• The product of the exponents

How do you determine how many times larger one number is than another in scientific notation?

• Add the coefficients and exponents

• Multiply the coefficients
