I assume you mean a button xy found in many calculators.
This is simply `raise x to the power of y` function that's quite useful as it allows you to raise to power, draw roots(square root is the same as x0.5) etc.
Suppose the two numbers are x and y. Then, the sum of THEIR reciprocals is 1/x + 1/y = y/xy + x/xy = (y + x)/xy = 7/25
xy - 4
0.5xy or xy/2
Suppose the numbers are x and y. The sum of their reciprocals = 1/x + 1/y = y/xy + x/xy = (y+x)/xy = (x+y)/xy = 10/30 = 1/3
xy-3 where x and y are the two numbers.
If the two numbers are x and y, thenthe square of the two numbers is one => (xy)^2 = 1 which implies that xy = +/-1.Then xy is a maximum => xy = 1.
The answer depends on whether xy are commutative numbers or operators in a permutation group.
Kyle XY was technically, a test tube baby. He didn't need an embylical chord, so he didn't have a belly button.
In the series kyle xy the part that is missing is his belly button

3-xy ...i think * * * * * Good try, but actually, it is xy - 3
xy - 4
xy +7
To enter an XY table on a TI-84 calculator, first press the "Y=" button to access the function editor. Then, input your desired function in one of the Y= slots. Next, press the "2nd" button followed by "TABLE" (which is the "GRAPH" button) to access the table view. You can then see the generated XY values based on your function and adjust the table settings if needed by pressing "2nd" and then "TABLE SETUP."
