Solve the problem.The "equilibrium constant" for a chemical reaction is often used to calculate the amounts of chemical substances that are present in a system. For a particular reaction, the equilibrium constant K is given by the formula 
where A, B, and C are the amounts (in arbitrary units) of chemicals a, b, and c. Calculate the equilibrium constant if A = 5, B = 4, and C = 6. Round your answer to three decimal places when necessary.
