n lg n is actually log₂ n, help i dont understand how to do this with microseconds :(

Exercise: 1. [10 points] Assume that an algorithm to solve a problem takes f(n) microseconds for some function f of the input size n. For each time t labeled across the top, determine the exact largest value of n which can be solved in time f(n) wheref(n) S t. me t- 1 second 1 hour 1 day 1 month 30 days 1,609,968 f(n) hi n2 g n 2" n lgn 2,755,147,513
