When they are scalar, xy and yx are equivalent. When they are vectors or matrices, they are not equivalent.

xy = x ÷x y = 1

This gives us the equations: n = xy = yx x != y (Note that for this example, the != stands for not equal to similar to some programming languages.) xy always equals yx due to the communtative property of multiplication. So there are actually an infinite number of answers. Some are given below: 6 = (2)(3) = (3)(2), 2 != 3 12 = (3)(4) = (4)(3), 3 != 4

That they are both algebraic expressions because they do not contain any equality signs.

If y = 0 then yx - 5 = 0*x - 5 = 0 - 5 = -5

Yes, xy is the same as yx, but should always be written as xy.

If you have a scientific calculator, it should have a key labelled either xy, or yx. Use this for powers.If you have a scientific calculator, it should have a key labelled either xy, or yx.

Ya tengo la (entrada) XY; me quedo con la (entrada) YX

xy and yx are identical so you have 2xy = 545 ie xy = 272.5. Possible answers 5 and 54.5, 10.9 and 25 etc

true

xy = x ÷x y = 1

Most scientific calculators don't have the capacity to simplify mathematical expressions, only to calculate based on known numbers. For calculating powers, there should be a key labelled something like xy or yx.

The correct order is XY, where X represents the larger chromosome and Y represents the smaller, sex-determining chromosome.

4xy + x3y + yx2 + yx + 3yx = x3y + x2y + 8xy = (xy)(x2y + x + 8)

No. There is no equality (or inequality) in the question: only a list of expressions.
