_______________________________________________________________________
 Scientific notation looks like this: _________________________________________


M = _________________________________________________

n = __________________________________________________
If the GIVEN number is > 1, the exponent (n) is _____________________.
Example: 230. is the same as 2.30 x 102

If the GIVEN number is < 1, the exponent (n) is _____________________.
Example: 0.23 is the same as 2.3 x 10-1
Standard Notation:
this is where a number is taken from ____________________
and put back to its ______________________ by moving the __________ the specified
number of times as shown by the ___________________. The exponent does NOT tell you
how many zeroes to add; the exponent tells you ___________________________________.
 Standard notation looks like a normal number.
Practice Problems
Write the following numbers in scientific notation.
