\frac{5+\sqrt{7}}{\left(5-\sqrt{7}\right)\left(5+\sqrt{7}\right)}
Irrazzjonalizza d-denominatur tal-\frac{1}{5-\sqrt{7}} billi timmultiplika in-numeratur u d-denominatur mill-5+\sqrt{7}.
\frac{5+\sqrt{7}}{5^{2}-\left(\sqrt{7}\right)^{2}}
Ikkunsidra li \left(5-\sqrt{7}\right)\left(5+\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{5+\sqrt{7}}{25-7}
Ikkwadra 5. Ikkwadra \sqrt{7}.
\frac{5+\sqrt{7}}{18}
Naqqas 7 minn 25 biex tikseb 18.
