Operations with Scientific Notation: Multiplication and Division

The video tutorial covers operations with scientific notation, focusing on multiplication and division. It explains the rules for handling exponents during these operations and provides multiple examples to illustrate the concepts. The tutorial also emphasizes the importance of expressing results in proper scientific notation.

What is the primary focus of today's lesson on scientific notation?

• None of the above

• Conversion to standard form

• Multiplying and dividing

• Adding and subtracting

When multiplying numbers in scientific notation, what happens to the exponents?

• They are multiplied

• They are added

• They are divided

• They are subtracted

In the example, how do you calculate the new exponent when multiplying 10^3 and 10^4?

• Add 3 and 4 to get 7

• Subtract 4 from 3 to get -1

• Multiply 3 and 4 to get 12

• None of the above

What is the correct scientific notation for a number 14.4 after adjusting the decimal?

• 14.4 x 10^-7

• 14.4 x 10^-8

• 1.44 x 10^-8

• 1.44 x 10^-7

When dividing in scientific notation, what operation is performed on the exponents?
