Question

prove that the following are irrational
(1) 1/root 2
(2) 7root5
(3) 6+root2



​

Answer 1

Step-by-step explanation:

1) let 1/√2 be rational number

then 1/√2=p/q

now √2=q/p×1

here √2 is a irrational number and

q/p×1 is a rational number

we know that an irrational number

can not be equal to an rational number

therefore 1/√2 is an irrational number
