Question

if X + 2019 is equals to y square and 2019 + Y is equals to x square then the product of X and Y is​

Answer 1

Here,

according to the question,

x+2019=y^2

so,y=√x+2019

and,

y+2019=x^2

so,x=√y+2019

now,

the product of x and y=√x+2019*√y+2019 =√(x+2019)*(y+2019)

Hope it will help you,
