1
**Scientific Notation A short-hand way of writing**

large and small numbers without writing all of the zeros.

2
**The Distance From the Sun to the Earth**

93,000,000

3
**Step 1 93,000,000 = 9.3000000 Move decimal left**

Leave only one number in front of decimal 93,000,000 =

4
Step 2 Write number without zeros 93,000,000 = 9.3

5
**Step 3 7 93,000,000 = 9.3 x 10 Count how many places you moved decimal**

Make sure that you write a power of ten 93,000,000 = 9.3 x 10 7

6
**The power of ten is 7 because the decimal moved 7 places. 7**

93,000,000 = 9.3 x 10 7

7
93,000, Standard Form 9.3 x Scientific Notation

8
**Practice Problem -----> -----> -----> ----->**

Write in scientific notation. Decide the power of ten. 98,500,000 = 9.85 x 10? 64,100,000,000 = 6.41 x 10? 279,000,000 = 2.79 x 10? 4,200,000 = 4.2 x 10? 9.85 x 107 -----> 6.41 x 1010 -----> 2.79 x 108 -----> -----> 4.2 x 106

9
**More Practice Problems**

On these, decide where the decimal will be moved. 734,000,000 = ______ x 108 870,000,000,000 = ______x 1011 90,000,000,000 = _____ x 1010 Answers 3) 9 x 1010 7.34 x 108 2) 8.7 x 1011

10
**Complete Practice Problems**

Write in scientific notation. 50,000 7,200,000 802,000,000,000 Answers 1) 5 x 104 2) 7.2 x 106 3) 8.02 x 1011

11
**Scientific Notation to Standard Form**

Move the decimal to the right 3.4 x 105 in scientific notation move the decimal ---> 340,000 in standard form

12
**Move the decimal to the right.**

Write in Standard Form Move the decimal to the right. 6.27 x 106 9.01 x 104 6,270,000 90,100

13
**What about a negative exponent?**

The sign of the exponent tells which direction to move the decimal. A positive exponent means you move the decimal to the right and a negative exponent means you move the decimal to the left.

14
**Negative Exponents in Scientific Notation**

When you have a negative exponent in scientific notation, you will move the decimal point to the LEFT!! 6.345 * 10¯6 is

15
**What would the following be in standard form…..**

3.45 * 10¯4 8 * 10¯8 * 10¯7 7.776 * 10¯11 2.209 * 10¯10

16
**Turn the following into scientific notation…**

0.3

17
**What is the Exponent? 2.352 * 10 2.147 * 10 8.5 * 10 9 * 10 3 * 10**

* 10 4.5 * 10
