An easy trick to solve this problem is just simplifying every term inside the root.
When a irrational number is multiplied with other irrational , the product need not be irrational number.
For example ,
when root 2 and root 8 are multiplied, product is root 16 i.e. 4
Here the product is 4 which is rational number.
The sum of two irrational numbers need not to be irrational
For example,
root 2 +(-root 2 )=0 which is a rational number
By knowing some of the basic properties , we can easily simplify any type of problem.
