It is referring to the male chromosome whereas the the female gender chromosome is XX.
In genetics, XY refers to the chromosomal pattern that typically determines male sex in many species, including humans. Males have one X and one Y chromosome, while females have two X chromosomes.
If you mean: xy2/xy then it can be simplified to y
XY is the male chromosomes, i dont know what the symbols for craziness are though
If x - 3y = 12, we can solve for x in terms of y: x = 12 + 3y. Then, to find xy, we multiply x by y: xy = y(12+3y) = 12y + 3y^2.

It means to have XY chromosomes, genetically.
xy - xy = 0
xy + xy = 2xy
XY
It is an expression in the form of: xy+7
X = 10 y is not a roman numeral
The answer depends on whether xy are commutative numbers or operators in a permutation group.
The GCF is xy
