  The number of bacteria after division
• How do you find the number of rounds of division in three hours?

  Convert hours to minutes and divide by 20
• How many rounds of division occur in three hours?

  Nine rounds of division
• What is the number of bacteria after three hours?

  512 bacteria
• How do you express 512 in standard form?

  1. 12 times $10^2$
• How many rounds of division occur in eight hours?

  24 rounds of division
• What is the number of bacteria after eight hours?

  16,777,216 bacteria
• How do you express 16,777,216 in standard form?

  1. 678 times $10^7$
• What are the steps to calculate the number of bacteria after a certain time?

  1. Determine the total time in minutes.
  2. Divide the total time by the division time (20 minutes).
  3. Use the formula $N =$$2^n$ to find the number of bacteria.
  4. Convert the result to standard form if required.
• What is the significance of the equation $N =$$2^n$ in bacterial growth?


  • It calculates the number of bacteria.
  • $n$ represents the number of division rounds.
  • Essential for predicting bacterial population growth.
