Introduction to Scientific Notation

6.879 x 10⁶

EXPLANATION-

1.  Move the decimal point to the left 6 places until

     it is after the first digit.  (Remember, the first

     number must be at least 1 but less than 10.)

2. The number of places that you move it becomes

     the exponent.  

3. The exponent is positive because it is a big

     number. 

4.  Zeroes at the end are not part of the answer

     because they were not significant.
