Question

Convert 93,100,000 from standard form to scientific notation.

Answer 1

9.3 * 10^7

Answer 2

To turn into scientific notation, simply put the number of significant figures out the front, with one significant figure before the decimal, and multiply by 10 raised to however many places you moved the decimal point.

Answer 3

Thank you guys

Answer 4

So 93,100,000 becomes 9.31 * 10^x where x is the number of places you've moved the decimal in 93,100,000.0 to 9.31.

Answer 5

(Noting of course, that if you move the decimal place to the right, x becomes a negative value).

Answer 6

Count the number of places you have to move the decimal point to get only 1 digit in the ones place. It will look like this. ?.? * 10^x. -x would mean if you had to move the decimal to the right to make it a while number.

Answer 7

Whole number*

Answer 8

That's correct Algebra1Flunk, however - you don't necessarily only want two significant figures. Sometimes things need more accuracy.

Answer 9

@SavannahSaturn , the answer to your previous question is quadrant IV, why did you delete it while I was working on it?

Answer 10

I was taught to simplify to two digits, but your right.

Answer 11

For instance, the difference between 9.31*10^7 and 9.3*10*7 is 0.01*10^7 or 1*10^5 - quite a big difference!

Answer 12

Sorry I didnt need it any more. But thank you hun for working on that @radar

Answer 13

Please don't delete answered questions SavannahSaturn, it's somewhat frowned upon as it means nobody can use it is as a reference in the future.
