__Scientific Notation Review__For Example say that we want to express a in scientific notation.

A) 3210000

First we look at the number and check the important numbers needed then we bring the decimal to the left

3.210000

Now remember how many spaces we moved to the left (6 times) and then remove the zeros

3.21

Now we times it by 10 to the power of 6

3.21 X 10

^{6 }

^{and now your done =) (Still don't understand it? then check out thie video}

^{Unitary Rates}

Example: If 1m = 100 cm

1m

1m

^{2}= 10000 cm (100 X 100) 1m

^{3}= 1000000 cm (100 X 100 X 100)Remember that when you square or cube the units, you also square the powers.
