Exploring Scientific Notation Concepts

This video tutorial covers the concept of scientific notation, explaining how to write numbers in this format and convert them back to standard form. It includes examples and a real-world application problem involving the calculation of blood consumed by fleas, demonstrating the practical use of scientific notation in science.

What is the range of the factor in scientific notation?

• Greater than or equal to 1 and less than 10

• Greater than 0 and less than or equal to 10

• Greater than 1 and less than 100

• Greater than 10 and less than 100

How is the exponent determined when converting a large number to scientific notation?

• By subtracting 1 from the number of digits in the number

• By counting how many times the decimal point moves to the left

• By counting how many times the decimal point moves to the right

• By adding the number of zeros in the number

In scientific notation, what does the exponent represent?

• The number of zeros after the decimal

• The number of times the decimal point has moved

• The total number of digits in the number

• The number of significant figures

What exponent sign is used for numbers between zero and one in scientific notation?

• Positive

• No exponent is used

• Zero

• Negative

What does a negative exponent in scientific notation indicate?

• A positive number

• A negative number

• A very small number

• A very large number

How do you convert a number in scientific notation with a negative exponent to standard form?

• Move the decimal point to the right

• Move the decimal point to the left

• Multiply by 10

• Divide by 10

What is 3.2 times 10 to the negative fourth power in standard form?

• 0.00032

• 0.0032

• 32

• 0.000032

What is the standard form of 7.9 times 10 to the fifth power?

• 790000

• 790

• 79000

• 7900

How much blood do 100 female fleas consume per day in liters?

• 0.0014 liters

• 0.014 liters

• 0.14 liters

• 1.4 liters

What is the more appropriate unit for the amount of blood consumed by the fleas each day?

• Gallons

• Milliliters

• Liters

• Cubic meters
