**Reiny**, Friday, January 25, 2013 at 12:23amexponents in this forum are indicated with the ^ symbol

So I am sure you meant

2.7x10^18 etc

The larger the exponent, the larger the number

If two numbers are have the same power of 10, then look at the factor in front to tell which is larger

e.g.

2.2x10^12 < 6.9x10^12

I am sure you can now sort them according to size
