Which of the following is not irrational number? (1)√2
(2)2/√6
(3)√36/1296
(4)-√6+6

Explanation:

hi !!

here i think all areirrational expect root 36/1296,

1. root 2= root 2= 1.414213562

2. 2/root 6= root 6 /3 = 0.8164965809

3. root 36/1296=1/6=1.66666667

4. - root 6+6= -2 root 3 = -3.464101615

so, they are extended and dont have exact value so all are irrational expect no. 3 because it can be expressed in 1/6 fraction form but others will come on root form.

Hope it helps...
