Find f' if x power 7 + y power 7 = 8xy

Calculus 1  bobpursley, Friday, February 25, 2011 at 7:08pm
x^7 + y^7 = 8xy
7x^6 dx+7y^6 dy=8y dx + 8x dy
dy(7y^68x)=dx(8y7x^6)
solve for dy/dx

x^7 + y^7 = 8xy
7x^6 + 7y^6 y' = 8y + 8x y'
8x y'  7y^6 y' = 7x^6  8y
y'(8x  7y^6) = 7x^6  8y
y' = (7x^6  8y)/(8x  7y^6)
