Passi tas-Soluzzjonijiet

Ikkombina \sqrt{3} u \sqrt{3} biex tikseb 2\sqrt{3}.

$$\frac{2\sqrt{3}}{\sqrt{2}-1}$$

Irrazzjonalizza d-denominatur tal-\frac{2\sqrt{3}}{\sqrt{2}-1} billi timmultiplika in-numeratur u d-denominatur mill-\sqrt{2}+1.

$$\frac{2\sqrt{3}\left(\sqrt{2}+1\right)}{\left(\sqrt{2}-1\right)\left(\sqrt{2}+1\right)}$$

Ikkunsidra li \left(\sqrt{2}-1\right)\left(\sqrt{2}+1\right). Il-multiplikazzjoni tista' tiġi ttrasformata fid-differenza tal-kwadrati li jużaw ir-regola: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.
