If z = f(x,y) = x4y3 +8x2y +y4 +5x, then the partial derivatives are ∂z ∂x = 4x3y3 +16xy +5 (Note: y fixed, x independent variable, z dependent variable) ∂z ∂y = 3x4y2 +8x2 +4y3 (Note: x fixed, y independent variable, z dependent variable) 2. If z = f(x,y) = (x2 +y3)10 +ln(x), then the partial derivatives are ∂z ∂x = 20x(x2 +y3 ... Web14 feb. 2024 · Notice that the order of arrangement of x, y, and z in the inequality x > y > z is the same as the order of arrangement of x, y^2, and z^4 in the inequality x > y^2 > z^4, so we want to test positive integers in this case. x = 10 y = 3 z = 1 Notice that 10 > 3 > 1 for x > y > z AND 10 > 9 > 1 for x > y^2 > z^4. We see that I could be true. II ...
