No, probably not.
6xy^2z^2 over 6xy^4z^4 or 1 over y^2z^2

The answer is 20.you get this answer by reading the instructions.
2/y
No, probably not.
6xy^2z^2 over 6xy^4z^4 or 1 over y^2z^2
-5+y
Y plus Y = 2Y simplified
3y
6y
If Y = y, then it is 9y4 or 9Y4. If Y is not the same as y, then you can't simplify it any.
y2-x2 = (y+x)(y-x)

15-y/4>10 15-10>y/4 [add y/4-10 to both sides] 5>y/4 [simplify lhs] 20>y [multiply by 4] y<20 [move y to lhs]
