log 4 64=3 log 2 6=2 ans = 3-2=1 Use the method of change of base Example y =log 2 4. This gives 4= 2^y Now change the base log 4= y log 2 y= log 4 /log 2. This you can get in the calculator.

just from looking at it, 64 and 4 are related. 64 is 4^3. and 4 is also 2^2 log_4 (4^3) - log_2 (2^2) 3log_4 (4) - 2log_2 (2) 3(1) - 2(1) 1
