# How To Multiply And Divide In Scientific Notation

How To Multiply And Divide In Scientific Notation. This video provides a basic introduction into scientific notation as it relates to multiplication and division. Divide and express the answer in scientific notation:

In either case, the answer must be converted to scientific notation. If after adding or subtracting the coefficients, the answer is not in scientific notation, then convert it to scientific notation. To multiply in scientific notation, you'll need to follow these three steps:

### Divide And Express The Answer In Scientific Notation:

When you multiply two numbers in scientific notation, you want to follow the same set of steps each time: Astronomers use very large numbers to describe distances in the universe and ages of stars and planets. Let’s multiply and divide numbers written in scientific notation.

### 9 3 × 103 10−2 9 3 × 10 3 10 − 2.

9×103 3×10−2 9 × 10 3 3 × 10 − 2. Divide 9 by 3 and use the quotient property to divide 103 10 3 by 10−2 10 − 2. The thing about slide rules is that they help you do chain.

### Then Multiply The Powers Of 10 By Adding The Exponents:

Dividing one number by another in scientific notation is really similar to multiplying two numbers in scientific notation, because we’re basically following the same. Start by dividing the coefficients: That is, 225 million =.

### 3 × 105 3 ×.

To divide two numbers in scientific notation, divide their coefficients and subtract their exponents. How to multiply numbers in scientific notation? Walk through these 4 simple steps to master these essential skills in this free math lesson!

### Use The Law Of Indices To Simplify The Powers.

To multiply two numbers expressed in scientific notation, simply multiply the numbers out front and add the exponents. To multiply numbers in scientific notation, first multiply the numbers that are not powers of 10 10 (the a in a×10n a × 10 n ). (9 ÷ 3) = 3.
