Whakaoti i te (1)sqrt{(sqrt{2})^2+(sqrt{7})^2}-sqrt{(sqrt{13})^2-(-3)^2}

$$( 1 ) \sqrt { ( \sqrt { 2 } ) ^ { 2 } + ( \sqrt { 7 } ) ^ { 2 } } - \sqrt { ( \sqrt { 13 } ) ^ { 2 } - ( - 3 ) ^ { 2 } }$$

Ngā Upane Otinga

Ko te pūrua o \sqrt{2} ko 2.

$$1\sqrt{2+\left(\sqrt{7}\right)^{2}}-\sqrt{\left(\sqrt{13}\right)^{2}-\left(-3\right)^{2}}$$

Ko te pūrua o \sqrt{7} ko 7.

$$1\sqrt{2+7}-\sqrt{\left(\sqrt{13}\right)^{2}-\left(-3\right)^{2}}$$

Tāpirihia te 2 ki te 7, ka 9.

$$1\sqrt{9}-\sqrt{\left(\sqrt{13}\right)^{2}-\left(-3\right)^{2}}$$

Tātaitia te pūtakerua o 9 kia tae ki 3.

$$1\times 3-\sqrt{\left(\sqrt{13}\right)^{2}-\left(-3\right)^{2}}$$

Whakareatia te 1 ki te 3, ka 3.

$$3-\sqrt{\left(\sqrt{13}\right)^{2}-\left(-3\right)^{2}}$$

Ko te pūrua o \sqrt{13} ko 13.

$$3-\sqrt{13-\left(-3\right)^{2}}$$

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

$$3-\sqrt{13-9}$$

Tangohia te 9 i te 13, ka 4.

$$3-\sqrt{4}$$

Tātaitia te pūtakerua o 4 kia tae ki 2.

$$3-2$$

Tangohia te 2 i te 3, ka 1.
