Answer:
Option E.
Step-by-step explanation:
The given expressions are
and
.
![x^2y^2=x\times x\times y\times y](https://tex.z-dn.net/?f=x%5E2y%5E2%3Dx%5Ctimes%20x%5Ctimes%20y%5Ctimes%20y)
![xy^3=x\times y\times y\times y](https://tex.z-dn.net/?f=xy%5E3%3Dx%5Ctimes%20y%5Ctimes%20y%5Ctimes%20y)
Greatest common factor of
and
is
![GCF=x\times y\times y=xy^2](https://tex.z-dn.net/?f=GCF%3Dx%5Ctimes%20y%5Ctimes%20y%3Dxy%5E2)
It is given that the greatest common factor of
and
is 45.
![xy^2=45](https://tex.z-dn.net/?f=xy%5E2%3D45)
![x=\dfrac{45}{y^2}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B45%7D%7By%5E2%7D)
x and y are positive integers.
For y=45,15,9,5 ![x=\dfrac{45}{y^2}\notin Z^+](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B45%7D%7By%5E2%7D%5Cnotin%20Z%5E%2B)
Only for y=3,
![x=\dfrac{45}{3^2}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B45%7D%7B3%5E2%7D)
![x=\dfrac{45}{9}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B45%7D%7B9%7D)
![x=5 \in Z^+](https://tex.z-dn.net/?f=x%3D5%20%5Cin%20Z%5E%2B)
The possible value of y is 3.
Therefore, the correct option is E.
