25\left(\sqrt{6}\right)^{2}-10\sqrt{6}\sqrt{5}+\left(\sqrt{5}\right)^{2}
Uża teorema binomjali \left(a-b\right)^{2}=a^{2}-2ab+b^{2} biex tespandi \left(5\sqrt{6}-\sqrt{5}\right)^{2}.
25\times 6-10\sqrt{6}\sqrt{5}+\left(\sqrt{5}\right)^{2}
Il-kwadrat ta' \sqrt{6} huwa 6.
150-10\sqrt{6}\sqrt{5}+\left(\sqrt{5}\right)^{2}
Immultiplika 25 u 6 biex tikseb 150.
150-10\sqrt{30}+\left(\sqrt{5}\right)^{2}
Biex timmultiplika \sqrt{6} u \sqrt{5}, immultiplika n-numri taħt l-għerq kwadrat.
150-10\sqrt{30}+5
Il-kwadrat ta' \sqrt{5} huwa 5.
155-10\sqrt{30}
Żid 150 u 5 biex tikseb 155.
