5-a/b
Then by talking lcm (5b-a)/b
The 3 will come to right side
(5b-a)/3b
As (5b- a) /3b is rational because they are forming p/q
And √2 is irrational so
1/3√2 5 is irrational

Answer of this question
Show that 1\3√2 +5 is irrational
5 3√2= a/b
5-a/b
Then by talking lcm (5b-a)/b
The 3 will come to right side
(5b-a)/3b
As (5b- a) /3b is rational because they are forming p/q
And √2 is irrational so
1/3√2 5 is irrational
