1/(root3+ root2)
=1/(root 3 +root 2) × (root 3 -root 2)/(root 3 -root 2)
=(root 3-root 2)/((root3)square -(root2)square)
=(root 3- root 2 )/(3-2)
=(root 3 - root 2 )
2/(root 5- root 3)
=2×(root 5+root 3) / (root 5 -root 3)(root 5- root 3)
2( root 5 + root 3)/5-3
2( root 5 + root 3)/2
root 5 +root 3
3/ root 2 -root 5
=3 × (root 2+ root 5 )/ (root 2 - root 5)( root 2 + root 5)
3(root 2+root 5) / 2-5
3(root 2 +root 5/ -3
root 2+ root5/-1 = - root 2 - root 5
1/(root3+root 2) - 2/(root 5 - root 3) - 3/( root 2 - root 5)
root 3 - root 2 - root 5 - root 3 + root 2 + root 5
