In working with numbers in scientifie notation, you should be able to convert them back to

Converting from Scientific to Decimal Notation

1. If the power of ten is positive, move the Example: 4.01 x 10 decimal point to the right the same number of places as the exponent. You might need to put in zeros as placeholders when you run out of digits. Putting in commas will make it easier to read a large number 4.01 (decimal moved eight places) 401.000,000 (ll in extra zeros)

2. If the power of ten is negative, move the m: Example: 3.2 x 10 decimal point to the left the same number of places as the exponent, again putting in zeros as needed. und? (decimal moved five places) 0,000032

Write each number in decimal notation.

a. The number of drops in a gallon of water: 9.085 x 10

b. The mass of an average dust particle: 7.53 x 10-10 grams Now let's see if you really understand scientific notation.

When a number written in scientific notation has a positive exponent on what can we say for sure about the number?

If a number between 0 and I is written in scientific notation, what can we say about the exponent on 10?

Fill in the blanks: If a number in scientific notation has a negative exponent on 10, to convert to decimal form, move the decimal place because the number is
