If log4 N=p and log12 N=q, show that log3 48= I tried so many times but it seems to be so tough for me... can anyone help?

This might be sending you the long way home but write out in terms of the logs given then change the base of all logs to base 3.

Hello, MichaelLight! My approach is worse that Pickslides' suggestion. I used the Base-Change formula. Divide numerator and denominator by . . Multiply by . . . .
