Céimeanna Réitigh

Fairsingigh \left(5\sqrt{2}\right)^{2}

$$5^{2}\left(\sqrt{2}\right)^{2}-\left(3\sqrt{2}\right)^{2}$$

Ríomh cumhacht 5 de 2 agus faigh 25.

$$25\left(\sqrt{2}\right)^{2}-\left(3\sqrt{2}\right)^{2}$$

Is é 2 uimhir chearnach \sqrt{2}.

$$25\times 2-\left(3\sqrt{2}\right)^{2}$$

Méadaigh 25 agus 2 chun 50 a fháil.

$$50-\left(3\sqrt{2}\right)^{2}$$

Fairsingigh \left(3\sqrt{2}\right)^{2}

$$50-3^{2}\left(\sqrt{2}\right)^{2}$$

Ríomh cumhacht 3 de 2 agus faigh 9.

$$50-9\left(\sqrt{2}\right)^{2}$$

Is é 2 uimhir chearnach \sqrt{2}.

$$50-9\times 2$$

Méadaigh 9 agus 2 chun 18 a fháil.

$$50-18$$

Dealaigh 18 ó 50 chun 32 a fháil.

$$32$$

Fachtóirigh
