**Reiny**, Tuesday, December 16, 2008 at 1:27amIn scientific notation, the decimal place is always after the first significant figure, in this case the 9

count the number of places you would have to move the decimal, that becomes your exponent of 10

so 9.0 x 10^10

**gr**, Tuesday, December 16, 2008 at 1:33amYou move decimal place after first significant figure and number of places you move does become your exponent but when you move right, exponent is negative and when you move left exponent is positive. Since in this case we are moving decimal to right by 10 places the exponent will be -10. Hence scientific notation would be 9.0*10^-10
