Question

√2 is irrational or not​

Answer 1

Answer:

√2 is irrational. because the square root of 2 is an irrational number, i.e. it cannot be given as the ratio of two integers.

Answer 2

Answer:

root 2 is irrational

Step-by-step explanation:

let root 2=a/b (where a and b are integers and are co prime)

then squaring both sides

2=a^2/b^2

a^2*2=b^2 --------(1)

2a=b

now let there be some integer c for 2a that satisfy the equation

putting c =2a in equation (1)

b=4c

that means it contradict that a and b are co-prime to each other.

Hence,our assumption is wrong

root 2 is irrational
