By giving counter example show that following statement are false
(a) p : Square of a real number is always integer
(b) p : The equation `x^2-9=0` does not have a root lying between 0 and 4

Text Solution

Verified by Experts

(a) Let a real number x=1.5
so, `x^2=2.25`, which is not an integer
So, p is false
(b) Given equation is `x^2-9=0`
Now, putting x=3 in `x^2-9`
`(3)^2-9`
`rArr 9-9`
`rArr 0`
So, 3 is a root of equation and lies between 0 and 4
So, p is false
