sema: 2log125_3log x=3
I am sorry sema, I don't understand your question. What is the underscore for?
I think it is a minus sign.
Here is a list of log identities that you can use.
http://en.wikipedia.org/wiki/List_of_logarithmic_identities
I haven't actually done your questin yet but I think that you will use the second one and the third one in the main list.
There will be a little more to it than that.
Use the hint below to help you solve the equation.
hint: if
log x=6
then
10^(logx) = 10^6
x=10^6
get back to me and tell me how you go.
