Hi, here is the solution....
When we simplify the radical expressions, we can add with the like terms.
For instance.
Sqrt(x^2) + 2x
Now can we add the terms? Ofcourse NO!
Now let's simplify the radical term sqrt(x^2)
sqrt(x^2) = (x^2)^1/2 = x
sqrt(x^2) + 2x
= x + 2x [Simplified]
Now can we add x and 2x?
Of course! We can add them since it is like term.
So we get x+2x = 3x. It ...
