Question

When can you add radical expression directly

Answer 1

Answer:

We can add or subtract radical expressions only when they have the same radicand and when they have the same radical type such as square roots.

Step-by-step explanation:

To add or subtract radicals, the indices and what is inside the radical (called the radicand) must be exactly the same. If the indices and radicands are the same, then add or subtract the terms in front of each like radical. If the indices or radicands are not the same, then you can not add or subtract the radicals.
