In a sample of rock, the ratio of number of `""^(206)Pb` to `""^(238)U` nuclei is found to be 0.5. The age of the rock is `(18//n)xx10^(9)(ln((3)/(2)))/(ln2)` year (Assume that all the Pb nuclides in he rock was produced due to the decay of Uranium nuclides and `T_(1//2)(""^(238)U)=4.5xx10^(9)` year). Find n.
