# How do you simplify # sqrt(27k^7q^8)#?

##### 1 Answer

There are different ways to look at how to simplify root statements - I present one of mine below and get to

#### Explanation:

When we're dealing with simplifying a term within a root, I like to use the "buddy" rule - which is, in order for a term to "escape" the root, it needs the number of buddies listed in the root (a square root is 2 buddies, a cube root is 3 buddies, etc).

Now let's break down each part of the terms inside the root piece by piece:

**27**

Putting it all together, we get:
