\frac{6\left(3-\sqrt{7}\right)}{\left(3+\sqrt{7}\right)\left(3-\sqrt{7}\right)}
Irrazzjonalizza d-denominatur tal-\frac{6}{3+\sqrt{7}} billi timmultiplika in-numeratur u d-denominatur mill-3-\sqrt{7}.
\frac{6\left(3-\sqrt{7}\right)}{3^{2}-\left(\sqrt{7}\right)^{2}}
Ikkunsidra li \left(3+\sqrt{7}\right)\left(3-\sqrt{7}\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}.
\frac{6\left(3-\sqrt{7}\right)}{9-7}
Ikkwadra 3. Ikkwadra \sqrt{7}.
\frac{6\left(3-\sqrt{7}\right)}{2}
Naqqas 7 minn 9 biex tikseb 2.
3\left(3-\sqrt{7}\right)
Iddividi 6\left(3-\sqrt{7}\right) b'2 biex tikseb3\left(3-\sqrt{7}\right).
9-3\sqrt{7}
Uża l-propjetà distributtiva biex timmultiplika 3 b'3-\sqrt{7}.
