Would I then plug in x and y into the original equation to find the minimum value? When I do that I get approximately 19.472, but my webwork homework says that is incorrect.

Find the minimum value of the function f(x,y= 25x^2+3y^2+20xy+10x+4y+10 subject to the constraint 5x^2+4xy=1. I solved fx=50x+20y+10 fy=6y+20x+4 gx=10x+4y gy=4x Then what?

Find the derivative of: y= 5^x + 15/x^6 I'm assuming I need to take the natural log of each side, but I get stuck after that part.
