We obtain a cosmological constant as a decreasing function of time and for $m, n > 0$, the value of cosmological ``constant'' for this model is found to be small and positive which is supported by the results from recent supernovae observations.9 pages, LaTex, typos addedGeneral Relativity and Quantum Cosmologytext
