For a number to be in scientific notation, it has to have two factors. The first factor must be between 1 and 10 and the second factor must be a power of 10.
i still dont understand
So when you multiply those two numbers you get 75.84 x 10^5
ohhhhh...so thts the answer in scientific notation! then whadda bout decimal?
That is not scientific notation because 75.84 is not between 1 and 10.
To make it between 1 and 10 we have to move the decimal point 1 place to the left making it 7.584
First you have to consider the number of significant digits, you go by the term with the lowest amount of significance (24x10^2 in this case has 2 significant digits).
Then its a simple matter of multiplication...
To convert from scientific notation to decimal notation, you move the decimal place by the amount indicated on the power. (ie, 1x10^2 becomes 100)
To go from decimal notation to scientific notation you figure out how many times you must multiply by 10 to reach a point where the number before the decimal is between 1 and 10.
