as √2 is an irrational number , we multiply 3 to √2 then it also becomes an irrational number

HopeithelpsyoupleasemarkmeasbrainliestAnswer:let us assume that 3√2 is rational

Then we have two integers a and b such that:

3√2=a/b

√2=a/3b

a,b and 3 are integers,hence a/3b is rational

Since a/3b is rational

hence√2 is rational

But this contadicts the fact that √2 is irrational.

This contradiction has arisen due to our incorrect assumption that 3√2 is rational.

Hence 3√2 is irrational
