x( y + 2 )^5 = 8

( y + 2 )^5 d/dx (x) + x d/dx(y+2)^5=d/dx 8

(y+2)^5 + 5x(y+2)^4 dy/dx=0

solve for dx/dy

I assume you want dy/dx.

Differentiate both sides of the equation with respect to x. You do not have to solve explicity for y first.

(y+2)^5 + 5x (y+2)^4 *dy/dx= 0

dy/dx = -(y+2)/(5x)

Thanks.

Thanks.
