Answer:
what is ur question exactly, ur question is missing some parts
Answer:

Step-by-step explanation:
we have to divide the given distance by 3.
Then we will be able to find the distance between markers.
Given distance is

Since, there are three markers,
So, we have to divide this distance by 3
So, the distance between markers is-

So, the distance between marker is

Now, we have to convert this into mixed number.
Then, the distance is-

To solve the problem we must know the basic exponential properties.
<h3>What are the basic exponent properties?</h3>


![\sqrt[m]{a^n} = a^{\frac{n}{m}}](https://tex.z-dn.net/?f=%5Csqrt%5Bm%5D%7Ba%5En%7D%20%3D%20a%5E%7B%5Cfrac%7Bn%7D%7Bm%7D%7D)


The expression can be written as
.
Given to us

Using the exponential property
,

Using the exponential property
,
![=x^9\times y^\frac{1}{3}\\\\=x^9\times \sqrt[3]{y}\\\\=x^9 \sqrt[3]{y}](https://tex.z-dn.net/?f=%3Dx%5E9%5Ctimes%20y%5E%5Cfrac%7B1%7D%7B3%7D%5C%5C%5C%5C%3Dx%5E9%5Ctimes%20%5Csqrt%5B3%5D%7By%7D%5C%5C%5C%5C%3Dx%5E9%20%5Csqrt%5B3%5D%7By%7D)
Hence, the expression can be written as
