Whakaoti i te 3*2*10^-4x-6*4*10^-6=0

$$3 \cdot 2 \times 10 ^ { - 4 } x - 6 \cdot 4 \times 10 ^ { - 6 } = 0$$

Whakaoti mō x

$$x=\frac{1}{25}=0.04$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 3 ki te 2, ka 6.

$$6\times 10^{-4}x-6\times 4\times 10^{-6}=0$$

Tātaihia te 10 mā te pū o -4, kia riro ko \frac{1}{10000}.

$$6\times \frac{1}{10000}x-6\times 4\times 10^{-6}=0$$

Whakareatia te 6 ki te \frac{1}{10000}, ka \frac{3}{5000}.

$$\frac{3}{5000}x-6\times 4\times 10^{-6}=0$$

Whakareatia te 6 ki te 4, ka 24.

$$\frac{3}{5000}x-24\times 10^{-6}=0$$

Tātaihia te 10 mā te pū o -6, kia riro ko \frac{1}{1000000}.

$$\frac{3}{5000}x-24\times \frac{1}{1000000}=0$$

Whakareatia te 24 ki te \frac{1}{1000000}, ka \frac{3}{125000}.

$$\frac{3}{5000}x-\frac{3}{125000}=0$$

Me tāpiri te \frac{3}{125000} ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$\frac{3}{5000}x=\frac{3}{125000}$$

Me whakarea ngā taha e rua ki te \frac{5000}{3}, te tau utu o \frac{3}{5000}.

$$x=\frac{3}{125000}\times \frac{5000}{3}$$

Whakareatia te \frac{3}{125000} ki te \frac{5000}{3}, ka \frac{1}{25}.

$$x=\frac{1}{25}$$
