Which choice is equivalent to the expression below? 215 +82/5 O A. 10/10 O O B. 16/10 O C. 16.15 O D. 10.5

Answer 1

You need to remember the following for adding Radicals:

$d\sqrt[n]{b}+a\sqrt[n]{b}=(a+d)\sqrt[n]{b}$

As you can see, the index of the Radicals must be the same and the Radicands must be the same
