  • What do you do with the coefficients when multiplying numbers in scientific notation?
    You multiply the coefficients together.
  • How do you handle the exponents when multiplying numbers in scientific notation?
    You add the exponents together.
  • What is the rule for dividing coefficients in scientific notation?
    You divide the coefficients.
  • What do you do with the exponents when dividing numbers in scientific notation?
    You subtract the exponents.
  • How do you write the product of (a × 10^x) and (b × 10^y) in scientific notation?
    It is written as (a × b) × 10^(x + y).
  • How do you write the quotient of (a × 10^x) divided by (b × 10^y) in scientific notation?
    It is written as (a/b) × 10^(x − y).
  • When multiplying or dividing in scientific notation, what determines the number of significant figures in your answer?
    The answer should have the same number of significant figures as the coefficient with the least significant figures.
  • Why is it important to consider significant figures in scientific notation calculations?
    It ensures the answer reflects the precision of the original measurements.
  • What is the first step when multiplying two numbers in scientific notation?
    Multiply the coefficients.
  • What is the first step when dividing two numbers in scientific notation?
    Divide the coefficients.
  • If you multiply 3 × 10^2 by 2 × 10^3, what is the exponent in the result?
    The exponent is 2 + 3 = 5.
  • If you divide 6 × 10^5 by 2 × 10^2, what is the exponent in the result?
    The exponent is 5 − 2 = 3.
  • What should you do after performing multiplication or division in scientific notation?
    Adjust the answer to reflect the correct number of significant figures.
  • What is the general formula for multiplying two numbers in scientific notation?
    (a × 10^x) × (b × 10^y) = (a × b) × 10^(x + y).
  • What is the general formula for dividing two numbers in scientific notation?
    (a × 10^x) / (b × 10^y) = (a/b) × 10^(x − y).
