Seems your question is a bit wrong 
your question should be" Rationalizethe denominator of  30/5root3-3root5"



[tex]30 /5 \sqrt{3}-3 \sqrt{5} =30/5 \sqrt{3} -3 \sqrt{5} *5 \sqrt{3} +3 \sqrt{5} /5 \sqrt{3} +3 \sqrt{5} [/tex]


$30(5 \sqrt{3} +3 \sqrt{5} )/ 5^{2} *3- 3^{2} *5 =30(5 \sqrt{3} +3 \sqrt{5} )/75-45$

$30(5 \sqrt{3} +3 \sqrt{5} ) /30=(5 \sqrt{3} +3 \sqrt{5} )$


Hence rationalised the denominator
