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

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

Enrhifo

$$2\sqrt{6}+5\approx 9.898979486$$

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.

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

Ehangu

$$2 \sqrt{6} + 5 = 9.898979486$$
