Question

I need help on this I need to find the restrictions and the rest

Answer 1

For this case we have the following:

`(5)/(xy)+(7)/(2x^2)`

And we can do the following:

`(1)/(x)((5)/(y)+(7)/(2x))=(1)/(x)((10x+7y)/(2xy))=(10x+7y)/(2x^2y)`

Then the conditions are:

`x_{}\\e0,y\\e0`

since we cant divide by 0 and for this reason thats the restriction
