Whakaoti i te (-5)^2-3^2+(2/3)^0/3^-2+frac{1{5}+1/2}

$$\frac { ( - 5 ) ^ { 2 } - 3 ^ { 2 } + ( \frac { 2 } { 3 } ) ^ { 0 } } { 3 ^ { - 2 } + \frac { 1 } { 5 } + \frac { 1 } { 2 } }$$

Ngā Upane Otinga

Tātaihia te -5 mā te pū o 2, kia riro ko 25.

$$\frac{25-3^{2}+\left(\frac{2}{3}\right)^{0}}{3^{-2}+\frac{1}{5}+\frac{1}{2}}$$

Tātaihia te 3 mā te pū o 2, kia riro ko 9.

$$\frac{25-9+\left(\frac{2}{3}\right)^{0}}{3^{-2}+\frac{1}{5}+\frac{1}{2}}$$

Tangohia te 9 i te 25, ka 16.

$$\frac{16+\left(\frac{2}{3}\right)^{0}}{3^{-2}+\frac{1}{5}+\frac{1}{2}}$$

Tātaihia te \frac{2}{3} mā te pū o 0, kia riro ko 1.

$$\frac{16+1}{3^{-2}+\frac{1}{5}+\frac{1}{2}}$$

Tāpirihia te 16 ki te 1, ka 17.

$$\frac{17}{3^{-2}+\frac{1}{5}+\frac{1}{2}}$$

Tātaihia te 3 mā te pū o -2, kia riro ko \frac{1}{9}.

$$\frac{17}{\frac{1}{9}+\frac{1}{5}+\frac{1}{2}}$$

Tāpirihia te \frac{1}{9} ki te \frac{1}{5}, ka \frac{14}{45}.

$$\frac{17}{\frac{14}{45}+\frac{1}{2}}$$

Tāpirihia te \frac{14}{45} ki te \frac{1}{2}, ka \frac{73}{90}.

$$\frac{17}{\frac{73}{90}}$$

Whakawehe 17 ki te \frac{73}{90} mā te whakarea 17 ki te tau huripoki o \frac{73}{90}.

$$17\times \frac{90}{73}$$

Whakareatia te 17 ki te \frac{90}{73}, ka \frac{1530}{73}.

$$\frac{1530}{73}$$

Tauwehe

$$\frac{2 \cdot 3 ^ {2} \cdot 5 \cdot 17}{73} = 20\frac{70}{73} = 20.958904109589042$$
