Multiply, and then simplify if possible. \( 9(\sqrt{6}-7) \) \( 9(\sqrt{6}-7)=\square \) (Simplify your answer. Type an exact answer, using radicals as needed.)

Calculate or simplify the expression \( 9*(\sqrt(6)-7) \). Calculate the value by following steps: - step0: Calculate: \(9\left(\sqrt{6}-7\right)\) - step1: Apply the distributive property: \(9\sqrt{6}-9\times 7\) - step2: Multiply the numbers: \(9\sqrt{6}-63\) The simplified form of \(9(\sqrt{6}-7)\) is \(9\sqrt{6}-63\).
