The 6 rules for converting to scientific notation are: 1. Place the decimal after the first non-zero digit. 2. Count the number of places the decimal has moved; this becomes the exponent. 3. If the original number was greater than 1, the exponent is positive; if less than 1, negative. 4. Write the number as a product of this digit and 10 raised to the power of the exponent. 5. Ensure only one non-zero digit is to the left of the decimal. 6. Simplify the notation if possible, maintaining accuracy.

FAQs & Answers

  1. What is scientific notation used for? Scientific notation is used to express very large or very small numbers in a compact form, making calculations and comparisons easier.
  2. How do you determine the exponent in scientific notation? The exponent is the number of places the decimal point moves to reach a position right after the first non-zero digit; it is positive if the original number is greater than one, and negative if it is less than one.
  3. Can scientific notation have more than one non-zero digit before the decimal? No, scientific notation requires only one non-zero digit to the left of the decimal to standardize the format.
