  3. Example 9-3c Objective Write numbers greater than 100 in scientific notation and in standard form

  4. Example 9-3c Vocabulary Scientific notation A number that is written as the product of a number and a power of ten 4.2 x 103

  5. Lesson 9 Contents Example 1Write a Number in Standard Form Example 2Write a Number in Scientific Notation

  6. Write in standard form. Example 9-1a  Write problem 3.4  106 Use calculator to solve 3.4 [ * ] 10 [ yx ] 6 = Put 3.4 in calculator Push multiplication sign Put the base of 10 in the calculator Answer: 3,400,000 Push the yx key Put the exponent of 6 in calculator Push the = sign 1/2

  7. Write in standard form. Example 9-1b  Answer: 73,000 1/2

  8. Example 9-2a Write 428,000 in scientific notation. Write problem 428,000 428,000. Remember: If there is no decimal in the number it is assumed to be to the right of the number 4.28 Draw arrow to the right of the first non-zero number Note: The zeros to the right of the 8 have no value so you do not have to include them Write the new number with the decimal where you placed the arrow 2/2

  9. Example 9-2a Write 428,000 in scientific notation. Put a multiplication symbol 428,000 428,000. Scientific notation uses the powers of 10, so put a factor of 10 4.28  10 105 Count how far the new decimal is from the old decimal Put the 5 as the exponent of 10 Answer: 4.28  105 2/2

  10. Example 9-2b * Write 1,750,000 in scientific notation. Answer: 1.75  106 2/2
