We here need to rationalise each term individually.
(1/root7 + root6)×(root7 - root6/root7 - root6)+
(1/root6 + root5)×(root6 - root5/root6 - root5)+
(1/root5 + root4)×(root5 - root4/root5 - root4)+
(1/root4 + root3)×(root4 - root3/root4 - root3)=
root7 - root6 + root6 - root5 + root5 - root4 + root4 - root 3=
cut all necessary terms,
on simplifying answer is
: root7-root3
=2.64-1.73
= 0.91
