Square root = exponent to power 1/2
sqrt(20x^6y^7)
= (20x^6y^7)^1/2
= 20^1/2 x^3 y^(7/2)
Ok first you mean median and 2 I think you would use because if you are make a statement about half the store then you are going to use the range
The corret anwser is actually going to be false! Your math teacher is wrong!
Answer:

Step-by-step explanation:
Use the 10th row of Pascal's Triangle to get you where you need to be. You need 10 rows because any polynomial raised to the 9th power has 10 terms. Those 10 terms are, in order:
1, 9, 36, 84, 126, 126, 84, 36, 9, 1
Setting up for the first 6 terms:

The 6th term is the last one. It goes on from there, but I stopped at the 6th term, since that is what you need.
Simplifying gives us:

and multiplying gives us:
