Whakaoti i te 3^2-3^-2/3^2+3^-2

$$\frac { 3 ^ { 2 } - 3 ^ { - 2 } } { 3 ^ { 2 } + 3 ^ { - 2 } }$$

Aromātai

$$\frac{40}{41}\approx 0.975609756$$

Ngā Upane Otinga

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

$$\frac{9-3^{-2}}{3^{2}+3^{-2}}$$

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

$$\frac{9-\frac{1}{9}}{3^{2}+3^{-2}}$$

Tangohia te \frac{1}{9} i te 9, ka \frac{80}{9}.

$$\frac{\frac{80}{9}}{3^{2}+3^{-2}}$$

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

$$\frac{\frac{80}{9}}{9+3^{-2}}$$

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

$$\frac{\frac{80}{9}}{9+\frac{1}{9}}$$

Tāpirihia te 9 ki te \frac{1}{9}, ka \frac{82}{9}.

$$\frac{\frac{80}{9}}{\frac{82}{9}}$$

Whakawehe \frac{80}{9} ki te \frac{82}{9} mā te whakarea \frac{80}{9} ki te tau huripoki o \frac{82}{9}.

$$\frac{80}{9}\times \frac{9}{82}$$

Whakareatia te \frac{80}{9} ki te \frac{9}{82}, ka \frac{40}{41}.

$$\frac{40}{41}$$

Tauwehe

$$\frac{2 ^ {3} \cdot 5}{41} = 0.975609756097561$$
