Using the properties of logarithms, we can simplify the expression as follows:
log(base 4)64 - log(base 4)16 + log(base 4)1/4
= 3 - 2 + (-2)
= -1

Now, we can use the change-of-base formula (logarithm base conversion formula) to check our answer:
log(base 4)1 = log(1)/log(4) ≈ -0.50

We can see that our answer is correct, rounded to two decimal places.
