Datrys {left(sqrt{3}-sqrt{2}right)}^2

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

Enrhifo

$$5-2\sqrt{6}\approx 0.101020514$$

Camau Ateb

Defnyddio'r theorem binomaidd \left(a-b\right)^{2}=a^{2}-2ab+b^{2} i ehangu'r \left(\sqrt{3}-\sqrt{2}\right)^{2}.

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

Sgwâr \sqrt{3} yw 3.

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

I luosi \sqrt{3} a \sqrt{2}, dylid lluosi'r rhifau dan yr ail isradd.

$$3-2\sqrt{6}+\left(\sqrt{2}\right)^{2}$$

Sgwâr \sqrt{2} yw 2.

$$3-2\sqrt{6}+2$$

Adio 3 a 2 i gael 5.

$$5-2\sqrt{6}$$
