Hi
I just'd like to know, if is this correctly solved. I think I started to understand that but I am not sure. If it's not correct, should you say me where's an error? Thanks. Greetings from Slovakia. :)
+128474 I get this :
[0.0000000027 / 81,000] / [ 100,000 / 0.000001 ] =
[ (2.7 x 10^-9) / ( 8.1 x 10^4)] / [ (1 x 10^5) / 1 x 10^-6) ] =
[ (2.7 x 10-9) / ( 8.1 x 10^4)] x [ (1x 10^-6)/ (1 x 10^5) ] =
[ 2.7 x 10^-15] / [ 8.1 x 10^9 ] =
(2.7 / 8.1) / ( 10^-15 / 10^9) =
_
(1/3) x 10^-24 ≈ 0.3 x 10^-24
Have a nice day/night.
