Answer:
Let's assume that 3√10 is rational no.
So,it can be expressed in the form of a/b form where a and b are integers.
So: 3√10=a/b
√10=a/3b
Since a and b are integers ,so a/3b is rational no. which implies that 3√10 is also rational no.
But it contradicts the fact that √10 is an irrational no.
Therefore our assumption is wrong, 3√10 is an irrational no.
