Question

5+2 root 6 ka whole root + 8-2root 15 ka whole root

Answer 1

Take the equation in the whole root as a+b/a-b whole square
As a+b whole square = a 2+b 2+2ab (a 2 means a square)
And a-b whole square = a 2+b 2-2ab
We can write the first equation as root2 2+root3 2+2(root2*root3) whole root
= root2 + root3 whole square whole root
The square cancels the root
So the ans for the first equation is root2+root3
Do the same for the second equation but just use a-b whole square
