Translate the given information into equations:
2L + 2W = 326
L = 2W - 5
Solve the system of equations.
2(2W - 5) + 2W = 326
4W - 10 + 2W = 326
6W - 10 = 326
6W = 336
W = 56
L = 2W - 5
L = 2(56) - 5
L = 107
Answer: Length: 107 ft; Width: 56 ft
Keeping the bases and adding the exponents, the simplified expression is:
![x^{\frac{4}{21}}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B4%7D%7B21%7D%7D)
<h3>How to solve a product of two terms with the same base and different exponents?</h3>
We keep the bases and add the exponents.
Hence:
![x^{-\frac{2}{3}} \times x^{\frac{6}{7}} = x^{-\frac{2}{3} + \frac{6}{7}} = x^{\frac{-14 + 18}{21}} = x^{\frac{4}{21}}](https://tex.z-dn.net/?f=x%5E%7B-%5Cfrac%7B2%7D%7B3%7D%7D%20%5Ctimes%20x%5E%7B%5Cfrac%7B6%7D%7B7%7D%7D%20%3D%20x%5E%7B-%5Cfrac%7B2%7D%7B3%7D%20%2B%20%5Cfrac%7B6%7D%7B7%7D%7D%20%3D%20x%5E%7B%5Cfrac%7B-14%20%2B%2018%7D%7B21%7D%7D%20%3D%20x%5E%7B%5Cfrac%7B4%7D%7B21%7D%7D)
