Large and Small Numbers as a Power of 10

What is scientific notation and why is it used?

• is a way to write very large and very small numbers. Its more efficient and convenient

• is a way to notate in science class. Its short and fast.

• is a way of writing medium sized numbers in science. It is expensive and slow to use

• Is a way of writing large and small fractions. It is more convenient and efficient.

• Yes. 2.8 is between 1 and 10, and move the decimal 6 places to the left.

• Yes. 2.8 is between 1 and 10, and move the decimal 6 places to the right.

• No. The exponent is incorrect. It is 6 places to the right, so the exponent should be positive 6.

• No. The number has 6 places to the left of 2.

• Yes, because when you convert standard form to scientific notation, you move the decimal to the right to get 3.2.
