Exploring Scientific Notation with Negative Exponents

Why do we use a negative exponent in scientific notation for numbers less than 1?

• Because the number is a whole number

• Because the number is exactly 1

• Because the number is very large

• Because the number is very small

What is the first step in converting a small number to scientific notation?

• Add a zero to the left of the number

• Move the decimal point to the right

• Move the decimal point to the left

• Multiply the number by 10

If you move the decimal point two places to the right, what will be the exponent in scientific notation?

• 2

• -10

• 10

• -2

How many times do you need to move the decimal point to convert 0.00002 to scientific notation?

• 4 times

• 3 times

• 2 times

• 5 times

What is the scientific notation of 0.00002?

• 2 x 10^-2

• 2 x 10^-3

• 2 x 10^-4

• 2 x 10^-5

Why is it important to include all significant digits when converting to scientific notation?

• To make the number larger

• To ensure accuracy

• To make the number smaller

• To simplify the number
