<<Ditanya>>

Hasil rasional…?

<<Jawab>>

frac{10}{2sqrt{3}+sqrt{7}}\= frac{10}{2sqrt{3}+sqrt{7}}times frac{2sqrt{3}-sqrt{7}}{2sqrt{3}-sqrt{7}}\=frac{20sqrt{3}-sqrt{7}}{4(sqrt{3})^2-(sqrt{7})^2}\=frac{20sqrt{3}-sqrt{7}}{4(3)-7}\=frac{20sqrt{3}-sqrt{7})}{12-7}\= frac{20sqrt{3}-sqrt{7}}{5}\=frac{4sqrt{3}-sqrt{7}}{1}\=4sqrt{3}-sqrt{7}\=4sqrt{3}-4sqrt{7}
