Whakaoti i te f(x)=1/2(3)^xtext{when}x=5

$$f ( x ) = \frac { 1 } { 2 } ( 3 ) ^ { x } \text { when } x = 5$$

Whakaoti mō f, x

$$x=5$$

$$f = \frac{243}{10} = 24\frac{3}{10} = 24.3$$

Ngā Upane Otinga

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

$$f\times 5=\frac{1}{2}\times 3^{5}$$

Tātaihia te 3 mā te pū o 5, kia riro ko 243.

$$f\times 5=\frac{1}{2}\times 243$$

Whakareatia te \frac{1}{2} ki te 243, ka \frac{243}{2}.

$$f\times 5=\frac{243}{2}$$

Whakawehea ngā taha e rua ki te 5.

$$f=\frac{\frac{243}{2}}{5}$$

Tuhia te \frac{\frac{243}{2}}{5} hei hautanga kotahi.

$$f=\frac{243}{2\times 5}$$

Whakareatia te 2 ki te 5, ka 10.

$$f=\frac{243}{10}$$

Kua oti te pūnaha te whakatau.

$$f=\frac{243}{10} x=5$$
