Answer:
Width = 128.5
Length = 171.5
Step-by-step explanation:
Perimeter = 2 × (Length + Width), Length = Width + 43
P = 2 × (W + 43 + W) = 2(2W + 43)
P = 600
2 ( 2W + 43) = 600
2W + 43 = 300
2W = 257
W = 128.5 meters
L = 128.5 + 43 = 171.5 meters

Answer:
![xy^\frac{2}{9} = x*\sqrt[9]{y^2}](https://tex.z-dn.net/?f=xy%5E%5Cfrac%7B2%7D%7B9%7D%20%3D%20x%2A%5Csqrt%5B9%5D%7By%5E2%7D)
Step-by-step explanation:
Given
![xy^\frac{2}{9}](https://tex.z-dn.net/?f=xy%5E%5Cfrac%7B2%7D%7B9%7D)
Required
The equivalent expression (see attachment)
We have:
![xy^\frac{2}{9}](https://tex.z-dn.net/?f=xy%5E%5Cfrac%7B2%7D%7B9%7D)
Split
![xy^\frac{2}{9} = x*y^\frac{2}{9}](https://tex.z-dn.net/?f=xy%5E%5Cfrac%7B2%7D%7B9%7D%20%3D%20x%2Ay%5E%5Cfrac%7B2%7D%7B9%7D)
Apply the following laws of indices
![y^\frac{m}{n} = \sqrt[n]{y^m}](https://tex.z-dn.net/?f=y%5E%5Cfrac%7Bm%7D%7Bn%7D%20%3D%20%5Csqrt%5Bn%5D%7By%5Em%7D)
So, we have:
![xy^\frac{2}{9} = x*\sqrt[9]{y^2}](https://tex.z-dn.net/?f=xy%5E%5Cfrac%7B2%7D%7B9%7D%20%3D%20x%2A%5Csqrt%5B9%5D%7By%5E2%7D)
<em>Hence (d) is correct</em>
