Answer:
instruction execution times at level 2 is kn
instruction execution times at level 2 is kn²
Explanation:
At each level, a factor of n is lost. It is given that it takes an interpreter n instructions to fetch, examine, and execute one instruction. So if at level-1 an instruction takes k nanoseconds to execute then at level-2 instruction takes kn to execute as at each level we tend to lose a factor of n. At level-3 instruction takes k(n.n) = kn² to execute.
