You haven't provided the expression or the choices, therefore, I cannot provide an exact answer.
However, I'll try to help you understand the concept so that you can solve the question you have
Like radicals are characterized by the following:
1- They both have the same root number (square root, cubic root , ...etc)
2- They both have the same radicand (meaning that the expression under the root is the same in both radicals)
Examples of like radicals:
3[tex] \sqrt{xyz} [/tex] and 7[tex] \sqrt{xyz} [/tex]
[tex] \sqrt[5]{x^2y} [/tex] and 3[tex] \sqrt[5]{x^2y} [/tex]
Check the choices you have. The one that satisfies the above two conditions would be your correct choice
Hope this helps :)
