Answer 2

Answer:

0

Step-by-step explanation:

x=5-4root6

1/x=1/5-4root6

Now we have to rationalize the denominator

1/5-4root6*5+4root6/5+4root6

=5+4root6/5^2-4root6^2

root and square cancel

=5+4root6/5^2-4×6

5+4root6/25-24

=5+4root6

Now,1-1/x

5-4root6-5+4root 6

4root 6 cancel on both sides

now 5-5=0

Ans=0
