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.
