4^n=26 find n     

 

When I open the calculator on my iPhone   

then turn the phone on its side   

then select 2nd functions    

one of the buttons is labeled logy   

 

What that does, you can choose your own base    

and the phone will provide the log of any number  

 

I found that log4(26) is  2.350219859 (rounded)  

 

check answer    

 

using the xy function on my iPhone    

 

42.350219859  =  25.99999999    

Close enough for government work.
