(3 points) Consider a 5-level computer in which all the levels are different. Each level has instructions that are m times as powerful as those of the level below it; that is, one level_r instruction can do the work of m level_(r-1) instructions. If a level_1 program requires k seconds to run, how long would equivalent programs take at level_ 5, assuming n level_r instructions are required to interpret a single level_( r+1) instruction
