Scientific Notation Operations and Concepts

This video tutorial explains how to multiply and divide expressions in scientific notation. It covers the process of handling the numbers and using exponent properties on the powers of ten. Two examples are provided: one for multiplication and one for division, demonstrating how to apply these techniques. The video emphasizes the importance of correctly handling exponents, especially when dealing with negative values, to ensure accurate results.

What is the first step when multiplying or dividing expressions in scientific notation?

• Multiply or divide the numbers out front

• Add the exponents

• Convert to standard form

• Subtract the exponents

When multiplying numbers in scientific notation, what should you do with the exponents?

• Multiply them

• Subtract them

• Ignore them

• Add them

What is the product of 3.4 x 10^5 and 2.7 x 10^-2 in scientific notation?
