Assume that each word of your machine has 64 bits. Assume that you can multiply two n-word numbers in time 5n2 with a standard algorithm. Assume that you can multiply two n-word numbers in time 10ns3 with a fancy" algorithm. For each part briefly justify and show your work (a) Approximately, how large does n have to be for the fancy algorithm to be better? (b) Approximately how many bits is that? (c) Approximately how many decimal digits is that
