Comparing Numbers in Scientific Notation

Mr. Holcomb explains scientific notation and its application in comparing numbers. The lesson covers inequalities, whole number comparisons, and exercises involving galaxy distances, subatomic particle lifetimes, and search engine data. Students learn to interpret and manipulate scientific notation, identify reasoning flaws, and perform calculations for large datasets.

What is the main focus of lesson 13?

• Comparison of numbers in scientific notation

• Addition of numbers in scientific notation

• Subtraction of numbers in scientific notation

• Multiplication of numbers in scientific notation

What is the principle behind comparing two numbers in scientific notation?

• Add them together

• Convert them to decimals

• Reduce them to whole numbers

• Convert them to fractions

If two whole numbers have different numbers of digits, which one is greater?

• The one with more digits

• They are equal

• Cannot be determined

• The one with fewer digits

Which galaxy is closer to Earth based on the given scientific notation?

• Triangulum Galaxy

• Andromeda Galaxy

• Foreign Actor Galaxy

• Milky Way Galaxy

Which subatomic particle has a longer average lifetime?

• Tau Lepton

• Neutral Pion

• Proton

• Neutron

When comparing two numbers with the same exponent in scientific notation, what should you compare?

• The exponents

• The decimal places

• The number of digits

• The coefficients

Why is Chris's reasoning flawed in comparing 5.3 and 5.30?

• He used incorrect arithmetic

• He focused on the number of digits

• He compared the coefficients

• He ignored the exponent
