Suppose a computer takes 1 nanosecond (=10 second) to execute each operation. Approximately how long will it take the computer to execute the following numbers of operations? Convert your answers into seconds, minutes, hours, days, weeks, or years, as appropriate. For example, instead of 250 nanoseconds, write 13 days. (a) log2 (170) (Round your answer, in seconds, to ten decimal places.) sec (b) 170 (Round your answer, in seconds, to eight decimal places.) sec (c) 170 log2 (170) (Round your answer, in seconds, to eight decimal places.) sec (d) 1702 (Round your answer, in seconds, to eight decimal places.) sec (e) 1708 (Round your answer, in years, to two decimal places.) (f) 2170 yr (Enter your answer, in years, using scientific notation. Round your coefficient to two decimal places.) 10 yr
