The output at a certain factory is Q(K, L) = 900K^3/4 L^1/4 units, where K is the capital investment measured in units of $1000 and L the size of the labor force measured in worker-hours. Compute the output if the capital investment is $100000 and the size of the labor force is 1705 worker-hours. By what factor will output change if both the level of capital investment and the size of the labor force are tripled
