Question

solve iii no question

Answer 1

i)1/root6+root5
 multiply numerator and denminator by (root6-roo5)
 1(root6-root5)/(root6+roo5)(root6-root5)

root6-root5/6-5
root6-root5
2.449-2.236
0.213



ii)6/root5+roo3
   multiply both by root5-root3
   6(root5-roo3)/(root5+root3)(root5-root3)
   6(root5-root3)/5-3
    3(2.336-1.732)
    3(0.504)
    1.512


iii)1/4root3-3root5
    multiply both by (4root3+3root5)
     (4root3+3root5)/ (4root3+3root5)4root3-3root5
      (4root3+3root5)/48-45
       (4root3+3root5)/3
       6.928+6.708/3
        13.636/3
         4.545
