If I wanted to solve:
if log_4 x=3, then log_8 x=
I apologize if this has been asked and answered before
Thanks for the responses, I was attempting to use the "search engine" on this site. I see that there is some sort of console that you are using, perhaps you can show me where I can find this? I am new to this site and I joined as my math skills are extremely under developed....I was wooed by the practice problem generator....Is this matlab output? I am extremely interested in this syntax and would love to see where you obtained this output. Thanks!
Even simpler
In[1]:= Solve[Log[4, x] == 3, x] Out[1]= {{x -> 64}} In[2]:= Log[8, 64] Out[2]= 2
In[2]:= Solve[{res == Log[8, x], Log[4, x] == 3}, {res, x}] Out[2]= {{res -> (3 Log[4])/Log[8], x -> 64}} In[3]:= FullSimplify[%] Out[3]= {{res -> 2, x -> 64}}
