-18y$\sqrt (3y)$
-2 * $\sqrt (81 * 3 * y^{2} * y)$ Step 1: Split Numbers Into Perfect Squares -2 * $\sqrt (9^{2} * 9 * 3 * y^{2} * y)$ Explanation: 81 = 9 * 9 * 9 = $9^{2}$ * 9 Step 2: Remove all perfect squared numbers/variables and put them on the outside -2(9)(y) * $\sqrt (3y)$ Step 3: Simplify -18y$\sqrt (3y)$
