Answer 2

Answer:  

Let us assume (5+7√2) is a rational number.  

5+7√2 = a/b  

Where , a,b are integers and  

b≠0  

=> 7√2 = a/b - 5  

=> 7√2 = (a-5b)/b  

=> √2 = (a-5b)/7b

Since , a,b are integers,  

(a-5b)/7b is a rational .So , √2 is rational .  

But ,this contradicts the  

fact that √2 is an irrational.  

Therefore,

5+7√2 is an irrational number.
