##### 1 Answer

#### Explanation:

The rules for radicals say that we can multiply the terms of the same order together, so we can move the

Multiplying the

A Google search on simplifying nested radicals turned up this page, which tells us that we can simplify this expression a little further using the rule;

Our expression is certainly the right form, but we need to check that we have reasonable

Therefore, we can use

***Note:** the page referenced above does not provide any proof for the equation mentioned, but if you square both sides, you can see that they are indeed equal.
