Math Problem Statement

but now you're on board the spaceship #218811928, and the captain is asking to solve tricky "ZP" (Z Planet) problem (you know what it means when captain is "asking"... that's an order):

(!!! Do Not use decimals/calculator. Present fractions in an exact format, for example, 7910779107 , 2292422924)

Now, find the slope of the tangent line to the curve

3x2+4xy4y3=35-3x^2+4xy-4y^3=-35

at the point (3,2)

  

!!! The challenge is that the easiest differentiation rule on Earth, d\differentialDxxn=nxn1\frac{d}{\differentialD x}x^{n}=nx^{n-1} , on Z planet is "twisted" as the following:

 d\differentialDxxn=n2xn1\frac{d}{\differentialD x}x^{n}=n^2x^{n-1}  (ddxconst=0ddxconst=0 , and the other rules have not been changed).
