Exploring Scientific Notation and Its Applications

What is the primary purpose of using Scientific Notation?

• To decrease the value of numbers

• To increase the value of numbers

• To make numbers easier to read by using exponents

What does shifting the decimal point to the left do to a number?

• Makes the number larger

• Converts the number to a fraction

• Makes the number smaller

Why is only one digit allowed to the left of the decimal in proper Scientific Notation?

• To make the number look bigger

• To extract all factors of 10

• To simplify the calculation

How many characters did it save to write 125,000,000 in Scientific Notation?

• Five characters

• Four characters

• Two characters

• Eight characters

What does the exponent in Scientific Notation represent?

• The order of magnitude of the number

• The decimal places to shift to the right

• The decimal places to shift to the left

What does a negative exponent in Scientific Notation indicate?

• The number is negative

• The number is very small

• The number is very large

What is the Scientific Notation of 0.00000095?

• 9.5 times 10 to the 7th

• 9.5 times 10 to the -7

• 0.95 times 10 to the -6

What is the result of shifting the decimal point one place to the right in a small number?

• The number becomes 10 times smaller

• The number becomes 10 times larger

• The number becomes a negative value

How do you convert a number in Scientific Notation to standard form with a positive exponent?

• Shift the decimal point to the left

• Shift the decimal point to the right

• Remove zeros from the right of the decimal

Why is Scientific Notation useful for comparing very large or very small numbers?

• It makes the numbers more complex

• It changes the value of the numbers

• It clarifies the order of magnitude
