If median of the scores \( \frac{x}{2}, \frac{x}{3}, \frac{x}{4}, \frac{x}{5} \), and \( \frac{x}{6} \) (where \( x \) \( >0 \) ) is 6 then \( \frac{x}{6} \) is

Simplify each expression. Assume that the variables represent any real numbers. Use the absolute value button only when necessary. (a) \( \sqrt{y^{16}}=\square \) (b) \( \sqrt{x^{18}}=\square \)

Multiply. \[ \begin{array}{l}(\sqrt{2}+7 \sqrt{5})(6 \sqrt{5}+\sqrt{2}) \\ \text { Simplify your answer as much as possible. }\end{array} \] II .

Simplify the expression. Assume that the variable is unrestricted and use absolute value symbols when necessary. \[ \sqrt{y^{2}-2 y+1} \]
