Ordering Numbers in Scientific Notation

This video tutorial explains how to order numbers in scientific notation. It provides examples using planets' distances from the sun and atoms' radii, demonstrating the process of comparing exponents and decimals. The tutorial emphasizes the importance of reading problem instructions carefully, especially regarding the order of least to greatest or greatest to least.

What is the first step in ordering numbers in scientific notation?

• Compare the exponents

• Compare the decimals

• Add the numbers

• Subtract the numbers

Which planet is closest to the sun based on the given scientific notation?

• Planet A: 7.783 x 10^8

• Planet B: 1.082 x 10^8

• Planet C: 5.899 x 10^9

• Planet D: 2.345 x 10^7

What is the second step in ordering numbers in scientific notation?

• Divide the numbers

• Compare the decimals

• Multiply the numbers

• Compare the exponents

Which of the following numbers is the largest when ordered from least to greatest?

• 5.899 x 10^9

• 7.783 x 10^8

• 3.456 x 10^7

• 1.082 x 10^8

What is the importance of comparing exponents first?

• It determines the overall magnitude

• It determines the order of decimals

• It identifies the largest number

• It simplifies the calculation

What is the significance of comparing decimals after exponents?

• It identifies the largest number

• It determines the overall magnitude

• It simplifies the calculation

• It helps in identifying the smallest number

Which of the following is the correct order of planets from least to greatest distance from the sun?

• Planet B, Planet A, Planet C

• Planet C, Planet A, Planet B

• Planet A, Planet C, Planet B

• Planet A, Planet B, Planet C

Which of the following is a correct statement about ordering numbers?

• Exponents are compared before decimals

• Decimals are compared before exponents

• Numbers are added before ordering

• Numbers are subtracted before ordering

What is the result of ordering 7.783 x 10^8, 1.082 x 10^8, and 5.899 x 10^9 from least to greatest?

• 1.082 x 10^8, 7.783 x 10^8, 5.899 x 10^9

• 7.783 x 10^8, 1.082 x 10^8, 5.899 x 10^9

• 1.082 x 10^8, 5.899 x 10^9, 7.783 x 10^8

• 5.899 x 10^9, 7.783 x 10^8, 1.082 x 10^8

What is the first step in ordering numbers with negative exponents?

• Add the numbers

• Subtract the numbers

• Compare the exponents

• Compare the decimals
