30/(5√3-3√5) × (5√3+3√5)/(5√3-3√5)
30(5√3+3√5 )/ (5√3-3√5)(5√3+3√5)
30(5√3+3√5)/(5√3)^2-(3√5 )^2
30(5√3+3√5)/25×3-9×5
30( 5√3+3√5 )/75-45
30(5√3+3√5 )/30 (30 and 30 get divided and cancelled)
=5√3+3√5
30(5√3+3√5 )/ (5√3-3√5)(5√3+3√5)
30(5√3+3√5)/(5√3)^2-(3√5 )^2
30(5√3+3√5)/25×3-9×5
30( 5√3+3√5 )/75-45
30(5√3+3√5 )/30 (30 and 30 get divided and cancelled)
=5√3+3√5
