Scientific Notation and Exponents

The video tutorial explains how to convert small numbers from standard form to scientific notation, focusing on using negative exponents. It provides examples, such as the diameter of a platelet and the length of an ant, to demonstrate the conversion process. The tutorial emphasizes moving the decimal point to the right of the first non-zero digit and counting the decimal places to determine the power of 10. It also covers converting numbers from scientific notation back to standard form by moving the decimal point to the left based on the negative exponent.

What is the key characteristic of a negative exponent in scientific notation?

• It indicates a large number.

• It indicates a small number.

• It indicates a positive number.

• It indicates a whole number.

When converting a small number to scientific notation, where should the decimal point be moved?

• To the left of the first non-zero number.

• To the right of the first non-zero number.

• To the right of the first zero.

• To the left of the first zero.

How do you determine the power of 10 when converting to scientific notation?

• By counting the number of decimal places moved.

• By counting the number of zeros.

• By counting the number of digits.

• By counting the number of ones.
