Oblicz u+v+w. odpowiedź podaj w najprostszej postaci.
b) u =
[tex] \frac{ 64x^{4} {y}^{2} - 60 {x}^{3} {y}^{2} }{ - 4 {x }^{3} {y}^{2} } [/tex]
V=
[tex] \frac{60x {y}^{3} - 85 {x}^{2} {y}^{3} }{5x {y}^{3} } [/tex]
W=
[tex] \frac{11 {x}^{3}y + 3 {x}^{2} y }{ - {x}^{2} y} [/tex]
b) u =
[tex] \frac{ 64x^{4} {y}^{2} - 60 {x}^{3} {y}^{2} }{ - 4 {x }^{3} {y}^{2} } [/tex]
V=
[tex] \frac{60x {y}^{3} - 85 {x}^{2} {y}^{3} }{5x {y}^{3} } [/tex]
W=
[tex] \frac{11 {x}^{3}y + 3 {x}^{2} y }{ - {x}^{2} y} [/tex]
[tex]u = \frac{64x^4y^2-60x^3y^2}{-4x^3y^2} =\frac{4x^3y^2(16x-15)}{-4x^3y^2}=-16x+15[/tex]
[tex]v = \frac{60xy^3-85x^2y^3}{5xy^3}= \frac{5xy^3(12-17x)}{5xy^3}=12-17x[/tex]
[tex]w = \frac{11x^3y+3x^2y}{-x^2y} =\frac{-x^2y(-11x-3)}{-x^2y} =-11x-3[/tex]
[tex]u + v + w = -16x + 15 +12-17x -11x-3 =24 - 44 x[/tex]
