The special way of writing large and small numbers that have many zeros - is called _______________ _______________. 2. The first part of a number written in scientific notation is a number between _______________ and _______________. 3. The last part is a _______________ of _______________. 4. A power of ten is nothing more than the number _____ (called the base) raised by a power. The power (or exponent) is the number up and to the _______________ of 10. 5. What is the base and the exponent of these numbers? 103 base _____ exponent _____ 10-5 base _____ exponent _____ 6. The _______________ exponent tells you how many times to write down the factor 10 and multiply to get the number. 7. The _______________ exponent tells you how many times to write down the factor 1/10 and multiply to get the number. 8. The positive exponent in a power of ten tells you the number of _______________ you multiply together to get the equivalent answer. 9. The negative exponent tells you the number of times you write down the factor _______________ and multiply to get the answer - and the number of _______________ in the answer that are to the _______________ of the decimal point. 10. 100 is another name for _____. 11. Multiplying by _______________ is the same as moving the decimal point one place to the right. 12. Multiplying a number by _______________ is the same as moving the decimal point one place to the left. 13. A number is written in scientific notation when it is written in this way: a number between _______________ and _______________ multiplied by a power of _______________. 14. Write 86,700,000,000,000,000,000,000 in scientific notation. 15. Why cant the above number be written as 867 x 1020? TO CONVERT FROM DECIMAL FORM TO SCIENTIFIC NOTATION 16. First, put a pointer (^) to the right of the first _______________ digit. 17. Second, count the spaces as you move from the _______________ (^) to the  old _______________ _______________. 18. Third, replace the _______________ (^) with the new decimal point and _______________ the number by 10 with an exponent that is the _______________ as the number of places you moved. Moving to the _______________ from the pointer (the new decimal point) gives a negative _______________; moving to the _______________ from the pointer gives a positive exponent. 19. Fourth, check to see if the new number is in _______________ _______________ - a number between one and ten multiplied by a power of ten. 20. Revising the four steps listed above will allow you to convert scientific notation to decimal form. Rewrite 1.6022 x 10-19 as a decimal number. 21. When using a calculator to do scientific notation problems, the calculator will usually not be able to handle exponents of ten that are _______________ than 99 or less than _______________. 22. To multiply two powers of 10, _______________ the exponents. 23. What is the answer to the following problem? (2.7 x 108) x (5.0 x 106) = _______________ 24. To divide one power of 10 by another power of 10, _______________ the exponent of the second (the _______________) from the exponent of the first (the _______________) 25.
