Izimpendulo ezinezimpande

Impendulo igcina izimpande zayo kuphela uma ingenamatemu angaphezu kwamabili futhi izinombolo ezikuyo zizincane ngokwanele. $\displaystyle 10\sqrt{2} + 15 \times 3\sqrt{3}$ ihlala isesimweni sempande futhi iba $\displaystyle 45\sqrt{3} + 10\sqrt{2}$. Kodwa $\displaystyle 99 \times \sqrt{999}$ ikhonjiswa njengedesimali, ngoba esimweni sempande izinombolo zayo zizoba zinkulu kakhulu.
