We calculate the entropy of 4-charge extremal black holes in Type IIAsupersting theory by using Sen's entropy function method. Using the low energyeffective actions in both $10D$ and 4D, we find precise agreements with theBekenstein-Hawking entropy of the black hole. We also calculate the higherorder corrections to the entropy and find that they depend on the exact form ofthe higher order corrections to the effective action.Comment: 12 pages, no figures, minor corrections, references added, to appear in PR
