1. x= 3/Y as a fraction btw
2. Same thing
Judging by the question I noticed that the two both share x^3 in common. You can divide x^4 by x^3 and get x as a result, and x^3 can still divide into itself.
Thus your answer should be C, x^3
You would need to find the GCF of 54 and 27.
Factors of 54: 1, 2, 3, 6, 9, 18, <u>27</u>, 54
Factors of 27: 1, 3, 9, <u>27</u>
so, the GCF is 27
