Question

1: Show that V2 is irrational.​

Answer 1

Answer:

let V2 is rational

means, v2 is equal to p/q and q is not equal to 0

Now, squaring the both side

v2 =p2/q2

v2^2=p2/q

we saw that there is no any command number

so, v2^2 not= p2/q

so, our supposition is wrong that v2 is a rational number

therefore, v2 is a irrational number
