Product Form 81.7 x 100,000

Scientific notation 81.7 x 10^5

**jim**, Wednesday, October 7, 2009 at 6:08pmYou typed both 81,700,00 and 81,700,000. I will assume you meant the second, because of the placement of the commas.

So Standard form 81,700,000

= 81.7 * 10^6

= 8.17 * 10^7

In scientific notation, we put only _one_ digit before the decimal place, so you will never see

81.7 x anything, or

36.7 x anything;

you always have to add the extra power of ten to make it

8.17 x something or

3.67 x something.

A million (1,000,000) is 10^6 - just count the zeroes as a rule of thumb.

We're looking to express 81.7 million, so 81.7 x 10^6 is accurate, but it's not in standard form. We need to move the decimal place left one and add a power of 10.
