Sqrt 80n^2 = sqrt 40x2xnxn = sqrt 20x2x2xnxn = sqrt 10x2x2x2xnxn = sqrt 5x2x2x2x2xnxn
Pull out numbers and letters in groups of 2
2x sqrt 5x2x2xnxn
2x2x sqrt 5xnxn
2x2xnx sqrt 5
Multiply the numbers and letters on the outside of the radical
4n x sqrt 5 is the final answer.
Answer: B
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You have that t<span>he largest doll is 12 inches tall. The height of each of the other dolls is 7/10 the height of the next larger doll. Therefore, you have:
We don't know the number of dolls, so:
x=12(7/10)^(n-1)
Where x is the height of the doll and n is the number of the doll
The answer is: </span>x=12(7/10)^(n-1)
