Whakaoti i te {l}{x=5}{y=2}{z=-2(x-y)^3}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { x = 5 }\\ { y = 2 }\\ { z = -2 {(x - y)} ^ {3} }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō x, y, z, a, b

$$b=-54$$

Ngā Upane Otinga

Whakaarohia te whārite tuatoru. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$z=-2\left(5-2\right)^{3}$$

Tangohia te 2 i te 5, ka 3.

$$z=-2\times 3^{3}$$

Tātaihia te 3 mā te pū o 3, kia riro ko 27.

$$z=-2\times 27$$

Whakareatia te -2 ki te 27, ka -54.

$$z=-54$$

Whakaarohia te whārite tuawhā. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$a=-54$$

Whakaarohia te whārite tuarima. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$b=-54$$

Kua oti te pūnaha te whakatau.

$$x=5 y=2 z=-54 a=-54 b=-54$$
