Jawab :

frac{(sqrt{3}-1) 4(sqrt{3} +4)}{2-sqrt{5} } = frac{(sqrt{3}-1) (4sqrt{3} +4)}{2-sqrt{5}} \= frac{4.3 + 4sqrt{3}-4sqrt{3}-4 }{2-sqrt{5} } \= frac{12-4}{2-sqrt{5} } . frac{2+sqrt{5}}{2+sqrt{5}} \= frac{16+12sqrt{5}-4sqrt{5} }{2^{2}+2sqrt{5}-2sqrt{5}-5} \= frac{16+8sqrt{5} }{4-5} \= 16+8sqrt{5}\ = 8(2+sqrt{5})
