For this case we must find the product of the following expression:

We combine using the product rule for radicals:
![\sqrt [n] {a} * \sqrt [n] {b} = \sqrt [n] {ab}](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%7D%20%2A%20%5Csqrt%20%5Bn%5D%20%7Bb%7D%20%3D%20%5Csqrt%20%5Bn%5D%20%7Bab%7D)
So, we have:

We rewrite the 216 as

By definition of properties of powers and roots we have:
![\sqrt [n] {a ^ n} = a ^ {\frac {n} {n}} = a](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20n%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bn%7D%20%7Bn%7D%7D%20%3D%20a)
Then, the expression is:

Answer:
Option D
Answer:
The missing number (i.e. the coefficient of x) is 5.
Step-by-step explanation:
5x - 8 - 9x = -4x + 8
-4x - 8 = -4x + 8
-8 ≠ 8
Answer: Choice A) 
==================================================
Work Shown:


When going from 234 to 9*26, the idea here is to factor where one factor is the largest perfect square possible. That way we can use the rule
to break up the root and simplify.
Answer:
720
Step-by-step explanation:
60 minutes in a hour. So add 30 for each 20 minutes so it would be 90 an hour so multiply 90 by 8
Answer:
x>=16
Step-by-step explanation:
Let's subtract 17 from each side!
17 + x>=33
-17 -17
This gets us x>=16
