For this case we must simplify the following expression:

We know that:
By definition of power properties we have to:
![\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20m%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bm%7D%20%7Bn%7D%7D)
Rewriting the given expression we have:

Answer:
Option A
// I am NOT sure about this, but I think it's part to part.
If it was part to whole ratio it will be out of total number of videos.
like ratio of videos that are drama to total videos.....
or ratio of videos that are not drama to total videos.....
You are talking part of each ratio and combining to a different one, so I think it's part to part.
//Again I am not sure about this. But kinda make sense.
Answer: 24
Step-by-step explanation: I think it is 24
Answer:
390 m (perpendicular to river) x 780 m (parallel to river)
Step-by-step explanation:
Let y be the length of the side parallel to the river, and let x be the length of the sides perpendicular to the river.
The total area and length of fence required are given by:
Rewriting the length of fence as a function of only x:
The value of x for which the derivate of L(x) is zero is the length of x that uses the least amount of fencing:
If x = 390 m, then:
The dimensions that will use the least amount of fencing are 390 m x 780 m
Answer:
x= 3.5 y=1.5
