(Number Theory) Assume that the Sieve of Eratosthenes needs roughly xln(ln(x)) "crossing out" operations in order to generate a list of all primes less than x. Note that this is slightly different than the estimate shown in class. You have a powerful computer that can perform 9.2 trillion "crossing-out" operations per second. How many years does it take this computer to generate a list of primes less than 10^33? Be sure to fully explain your computations.

The value of . Total number of "crossing out

(Number Theory) Assume that the Sieve of Eratosthenes needs roughly xln(ln(x)) “crossing out” operations in command to breed a inventory of whole primes hither than x. Note that this is subordinately contrariant than the revere shown in assort.

You possess a mighty computer that can transact 9.2 trillion “crossing-out” operations per promote. How divers years does it engage this computer to breed a inventory of primes hither than 10^33? Be secure to easily interpret your computations.

Total number of “crossing out” operations required to breed whole primes

Since, Time needed to transact  “crossing out” operations =

So, Time needed to transact  “crossing out” operations

Thus, Time needed to transact  “crossing out” operations
