Simplify the following expression. Assume $\displaystyle {x}>{0}$.
$\displaystyle {\left({36}{x}\right)}^{{{1}/{2}}}\cdot{\left({6}{x}^{{{1}/{7}}}\right)}$

The answer can be written in the form $\displaystyle {C}{x}^{{a}}$ where
the coefficient $\displaystyle {C}$ is: Preview Question 6 Part 1 of 2  
and the exponent $\displaystyle {a}$ is: Preview Question 6 Part 2 of 2   Note: enter the exponent as a reduced fraction or integer.
