$$\left. \begin{array} { l } { A = 423 \times 10 ^ { 5 } + 0,6 \times 10 ^ { 7 } } \\ { B = \frac { 25 \times 10 ^ { 10 } + 0,5 \times 10 ^ { 11 } } { 6 \times 10 ^ { 7 } } } \end{array} \right.$$

Whakaoti mō A, B

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Tātaihia te 10 mā te pū o 5, kia riro ko 100000.

$$A=423\times 100000+0.6\times 10^{7}$$

Whakareatia te 423 ki te 100000, ka 42300000.

$$A=42300000+0.6\times 10^{7}$$

Tātaihia te 10 mā te pū o 7, kia riro ko 10000000.

$$A=42300000+0.6\times 10000000$$

Whakareatia te 0.6 ki te 10000000, ka 6000000.

$$A=42300000+6000000$$

Tāpirihia te 42300000 ki te 6000000, ka 48300000.

$$A=48300000$$

Whakaarohia te whārite tuarua. Tātaihia te 10 mā te pū o 10, kia riro ko 10000000000.

$$B=\frac{25\times 10000000000+0.5\times 10^{11}}{6\times 10^{7}}$$

Whakareatia te 25 ki te 10000000000, ka 250000000000.

$$B=\frac{250000000000+0.5\times 10^{11}}{6\times 10^{7}}$$

Tātaihia te 10 mā te pū o 11, kia riro ko 100000000000.

$$B=\frac{250000000000+0.5\times 100000000000}{6\times 10^{7}}$$

Whakareatia te 0.5 ki te 100000000000, ka 50000000000.

$$B=\frac{250000000000+50000000000}{6\times 10^{7}}$$

Tāpirihia te 250000000000 ki te 50000000000, ka 300000000000.

$$B=\frac{300000000000}{6\times 10^{7}}$$

Tātaihia te 10 mā te pū o 7, kia riro ko 10000000.

$$B=\frac{300000000000}{6\times 10000000}$$

Whakareatia te 6 ki te 10000000, ka 60000000.

$$B=\frac{300000000000}{60000000}$$

Whakawehea te 300000000000 ki te 60000000, kia riro ko 5000.

$$B=5000$$

Kua oti te pūnaha te whakatau.

$$A=48300000 B=5000$$
