Answer: The required sum is
Step-by-step explanation: We are given to find the sum of the following two radical expressions:
Since both the expressions involve the same radical term, so we can simply take the radical term common and add the rest of the terms to get the result.
The summation is as follows:
Thus, the required sum is

Step-by-step explanation:
Like terms must have the same variable, in this case x, and the same exponent, in this case 2. Since the original term is , the like terms will be those that contain
, regardless of whether their coefficient or sign is different.
Analyzing the options:
A.-
We have the same variable and the same exponent , so it is a like term.
B.
You have the same variable x but not the same exponent. So it's not a like term of
C.
Same variable but as in the previous case, the exponent is different, it is a 3 and it should be a 2, so it is not a similar or like term.
D.
In this option we do have the , so it is a like term of
E.
It is also a like term because it contains the .
In summary the like terms are:
A.-
D.
E.
For this case we have the following functions:
We must find By definition of composition of functions we have:
So:
Thus, the correct option is option C.
