Understanding Scientific Notation Concepts

The video tutorial explains how to multiply numbers and express the result in scientific notation. It begins by defining scientific notation and then demonstrates multiplication using associative and commutative properties. The tutorial calculates the product of two numbers and adjusts the result to ensure it is in proper scientific notation.

What is the basic form of a number in scientific notation?

• a divided by 10 to some power

• a plus 10 to some power

• a minus 10 to some power

• a times 10 to some power

Which of the following is true about numbers in scientific notation?

• a is greater than or equal to 10

• a is equal to 0

• a is less than 1

• a is greater than or equal to 1 and less than 10

What is the first step in multiplying numbers in scientific notation?

• Add the exponents

• Multiply the coefficients

• Subtract the exponents

• Divide the coefficients

Which property allows us to rearrange the multiplication of numbers?

• Distributive property

• Associative property

• Commutative property

• Identity property

What is the result of multiplying 10 to the sixth by 10 to the negative fifth?

• 10 to the eleventh power
