Logarithmic functions

I have a question regarding logarithmic functions-- the problem is this log base 4 (64x^5) this is to be expanded. I have factored 64 but I still am not coming up with the correct answer. I have 4+5 log 4 x. The book has 3+5log4x. What am I doing wrong???? Is the book wrong? I have been trying to figure this out but just
