Given the expression:
You need to remember that Equivalent Expressions represent the same, but they have different forms.
Therefore, you can find an equivalent expression to the given expression by simplifying it.
You can identify that the square roots have the same Radicand (the number inside the root). Therefore, you can combine the like terms by adding the coefficients.
Remember that like terms have the same variables with the same exponents.
Then, you get:
Hence, the answer is: Option C.
