Let x, y and z be three integers. Suppose that the binary representation of x uses n bits, the binary representation of y uses n bits and the binary representation of z uses n bits. How many bits does the binary representation of the product xyz use? Note: Provide all details of your solution and give your final answer using Θ-notation.
I figured out if x y and z are all the maximal bit number then x=y=z=2^n-1
Not sure how to proceed or deliver the answer in Θ-notation
