Determine whether the equation is exact. If it is$,$ then solve it$.$

$[2ycos(xy)\frac{9}{\sqrt[\phantom{2}]{1-x^2}}]dx[2xcos(xy)-3y^{-\frac{3}{7}}]dy=0$

Select the correct choice below and, if necessary, fill in the answer box

A$.$ The equation is exact and an implicit solution in the form $F(x,y)$

$($Type an expression using $x$ and $y$ as the variables.$)$

B$.$ The equation is not exact.
