Question

( i v ) sarg ( a^{3}-5 sqrt{5} b^{3} )
( =(-sqrt{3}-a)^{3}-(sqrt{5} b)^{3} )
( =(sqrt{3} a-sqrt{5} b)left[(sqrt{3 a})^{2}+sqrt{39} cdot sqrt{5 b}+(sqrt{5}+2)^{2}right] )
( =(-sqrt{3} a-sqrt{5} b)left[(sqrt{3} a+sqrt{5} b)^{2}-sqrt{3} a sqrt{5} bright] )
( =(sqrt{3} a-sqrt{5} b)left{(sqrt{3} a+sqrt{5} b)^{2}-sqrt{15 a b}right} )
( frac{13+sqrt{1-4 n})}{(3+sqrt{1-4 x})} )
