Answer:

Step-by-stepexplanation

1. ans=(729)^-1/6

         =(3^6)^-1/6

          = 3^6*(-1/6)

          =3^-1

          = 1/3

2.ans=(2root7-3root3)

3.ans=((root5+root2)^2)/3

4.ans=(root14-7*root10+14*root2)/7

5.ans=1/root2+1

          = 1/1.414+1

          =1/2.414

           = 500/1207
