We have to find the area first
12 x 18=216 square feet
we do 216* $ 1.39= $ 300.24
Answer:hahahahh bithch4
Step-by-step explanation:
For this case we must indicate an expression equivalent to:

For properties of powers we have to:

So, the above expression can be rewritten as:

Thus, the resulting expression is: 
Answer:

Option D
Answer:
![xy^3 \sqrt[4]{y^3}](https://tex.z-dn.net/?f=xy%5E3%20%5Csqrt%5B4%5D%7By%5E3%7D)
Step-by-step explanation:
Recall the exponent property
.
We can use this property to break the problem down:
![\sqrt[4]{x^4y^{15}}=\sqrt[4]{x\cdot x\cdot x\cdot x\cdot y^3\cdot y^3\cdot y^3\cdot y^3\cdot y^3}=\boxed{xy^3 \sqrt[4]{y^3}}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx%5E4y%5E%7B15%7D%7D%3D%5Csqrt%5B4%5D%7Bx%5Ccdot%20x%5Ccdot%20x%5Ccdot%20x%5Ccdot%20y%5E3%5Ccdot%20y%5E3%5Ccdot%20y%5E3%5Ccdot%20y%5E3%5Ccdot%20y%5E3%7D%3D%5Cboxed%7Bxy%5E3%20%5Csqrt%5B4%5D%7By%5E3%7D%7D)
