Let 5√6 is an rational no. Where a and b are integers and b is not equal to 0 such that 5√6=a/b Then we get √6=a/5b Since, 5,a,and b are integers a/5b is rational so √6 is rational. This contradiction has arisen due to our wrong assumption . So we conclude that 5√6 is iraational no.

Let 5√6 is an rational no. Where p and q are integers and q is not equal to 0 such that 5√6=p/q we get √2=a/3b Since 3,a,b are integers , a/3b is rational,and so √2 is rational. But this contradicts fact that √2 is irrational. So, we conclude that 5√6 is irrational no.

5√6=p/q ;q is not equal to 0 &P&Q are coprime with each other P/Q=5√7 P-7/q=√5 an rational number will never be equal to irrational number so 5√6 is irrational number
