\frac{12\left(3+\sqrt{5}\right)}{\left(3-\sqrt{5}\right)\left(3+\sqrt{5}\right)}
Irrazzjonalizza d-denominatur tal-\frac{12}{3-\sqrt{5}} billi timmultiplika in-numeratur u d-denominatur mill-3+\sqrt{5}.
\frac{12\left(3+\sqrt{5}\right)}{3^{2}-\left(\sqrt{5}\right)^{2}}
Ikkunsidra li \left(3-\sqrt{5}\right)\left(3+\sqrt{5}\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{12\left(3+\sqrt{5}\right)}{9-5}
Ikkwadra 3. Ikkwadra \sqrt{5}.
\frac{12\left(3+\sqrt{5}\right)}{4}
Naqqas 5 minn 9 biex tikseb 4.
3\left(3+\sqrt{5}\right)
Iddividi 12\left(3+\sqrt{5}\right) b'4 biex tikseb3\left(3+\sqrt{5}\right).
9+3\sqrt{5}
Uża l-propjetà distributtiva biex timmultiplika 3 b'3+\sqrt{5}.
