Question 96798
Step 1: you solve for the right side of the problem 
        ( I typed it in as (log(16)/4) + (log(49)/2) ) 
        logy = .301029957... + .84509804... 
        logy = 1.146128036...
Step 2: Do the inverse log of that answer 
        (Inverse log is typically the 2nd then the log key (it's {{{10^x}}} )
        y = 14
