# Scientific Notation

It is customary in scientific notation to use $\times$ as the multiplication sign, even though we avoid using this sign elsewhere in algebra. Scientific notation is a useful way of writing very large or very small numbers. It is used often in the sciences to make calculations easier. This answer must be changed to scientific notation. Change the 30 into its scientific notation form. To divide numbers in scientific notation, simply divide the numbers that are between 1 and 10 to get the first number and subtract the powers of ten to get the second number. Divide the following and express the answers in scientific notation. Lawrence Perez, from Saddleback College, and his assistant Charlie, give this pre-algebra two-part lesson on scientific notation.

Notes/HW Blank 1. Zero and Negative Exponents. 2. Product and Quotient Rules. 3. Power to a Power. 4. Law of Exponents Practice. 5. Scientific notation uses powers of ten expressed as exponents, so you need a little background before you can jump in. Numbers starting with a 1 and followed by only 0s such 10, 100, 1,000, 10,000, and so forth are called powers of ten, and they’re easy to represent as exponents. You can divide numbers in scientific notation as well. Step 1 - Divide the numbers. Step 2 - Divide the powers of 10. Just subtract the exponents. Remember, s ometimes after dividing numbers in scientific notation the answer is no longer in scientific notation so you may need to make an adjustment. This section covers: Exponents and Powers Radicals Roots Simplifying and Rationalizing Radicals Scientific Notation More Practice Note that we’ll talk about Exponents and Radicals in Algebra here. Exponents and Powers Actually, I think students have difficulty with powers, or exponents, since they are so small. They really aren’t difficult.

Just like exponents, scientific notation was invented so that we don't need to waste a bunch of time writing out numbers like our fingers just cramped typing all those zeros. Instead, we can write this crazy long number as 2.5 × 10 34. How It Works. Scientific notation has three parts to it: the coefficient, the base, and the exponent.

The number of decimal places you move will be the exponent on the. If the decimal is being moved to the right, the exponent will be negative.
