Whakaoti i te ((2-1/4)*(3-1/2))^2-sqrt{9}

$$( ( 2 - \frac { 1 } { 4 } ) \cdot ( 3 - \frac { 1 } { 2 } ) ) ^ { 2 } - \sqrt { 9 }$$

Aromātai

$$\frac{1033}{64}=16.140625$$

Ngā Upane Otinga

Tangohia te \frac{1}{4} i te 2, ka \frac{7}{4}.

$$\left(\frac{7}{4}\left(3-\frac{1}{2}\right)\right)^{2}-\sqrt{9}$$

Tangohia te \frac{1}{2} i te 3, ka \frac{5}{2}.

$$\left(\frac{7}{4}\times \frac{5}{2}\right)^{2}-\sqrt{9}$$

Whakareatia te \frac{7}{4} ki te \frac{5}{2}, ka \frac{35}{8}.

$$\left(\frac{35}{8}\right)^{2}-\sqrt{9}$$

Tātaihia te \frac{35}{8} mā te pū o 2, kia riro ko \frac{1225}{64}.

$$\frac{1225}{64}-\sqrt{9}$$

Tātaitia te pūtakerua o 9 kia tae ki 3.

$$\frac{1225}{64}-3$$

Tangohia te 3 i te \frac{1225}{64}, ka \frac{1033}{64}.

$$\frac{1033}{64}$$

Tauwehe

$$\frac{1033}{2 ^ {6}} = 16\frac{9}{64} = 16.140625$$
