• In the scientific notation method, all numbers
  are expressed as the product of a number between

• 520 000 g 5.2 x 105 g
• 0.0937 m 9.37 x 10-2 m
• Now lets work on s 1 2 on worksheet

If the number is greater than 1.

• Then the scientific notation is going to be a
  positive number
• 310000
• 3.1 x 105
• If the exponent is positive then the number is
  greater than 1
• 3 x 104
• 30,000

4
If the number is less than 1.

• Then the scientific notation is going to be a
  negative number
• .00004
• 4.0 x 10 -5
• If the exponent is negative then the number is
  going to be less than 1
• 5.93 x 10 -5
• .0000593
