Ordering Numbers in Scientific Notation (Part 2)

The video tutorial explains how to order numbers in scientific notation by first comparing the powers of 10 and then the coefficients. It uses the example of ordering planets by their diameters, demonstrating that Mercury and Mars have the smallest powers of 10, followed by Venus and Earth, with Jupiter having the largest. The lesson concludes with a summary of the ordered planets and reinforces the concept of scientific notation.

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

• Convert them to decimal form

• Add the numbers together

• Compare the powers of 10 first

• Compare the coefficients first

Why is Venus not the smallest planet despite having the smallest coefficient?

• It is closer to the Sun

• It has the largest power of 10

• It has a larger power of 10 than Mercury and Mars

• It has the smallest power of 10

Which planet is smaller based on scientific notation: Mercury or Mars?

• Mercury, because it has a smaller power of 10

• Mercury, because it has a smaller coefficient

• Mars, because it has a smaller power of 10

• Mars, because it has a larger coefficient

Which planet comes last when ordering by diameter in scientific notation?

• Jupiter

• Earth

• Venus

• Mars

What is the correct order of planets by diameter from smallest to largest?

• Earth, Venus, Mercury, Mars, Jupiter

• Venus, Earth, Mars, Mercury, Jupiter

• Mercury, Mars, Venus, Earth, Jupiter

• Mars, Mercury, Venus, Earth, Jupiter
