(5.5)(8) x 10^-10
= 44 x 10^-10
= 4.4 x 10^-9
how did you get +10 ????
scientific notation consists of a number with a single digit, followed by a decimal x 10^(some exponent)
scientific notation for (5.5*10^-8)(8*10^-2)
I got (5.5*8)(10^-8*10^-2)
then
44*10^10
What am I doing wrong?

I actually had -10, forgot to put it above. Thank you. I had stopped at the 44 x 10^-10 and didn't go one step further. Thanks again Reiny.
