Ta có: `x^2017 + y^2017 = 2017`
`=> (x^2017 + y^2017)^2 = 2017^2`
`=> x^4034 + 2x^2017y^2017 + y^4034 = 2017^2`
`=> 2x^2017y^2017 = 2017^2 - 4034`
`=> 2x^2017 y^2017 = 2017(2017 -2)`
`=> x^2017y^2017 = (2017 . 2015)/2`
Mặt khác, `A = x^6051 + y^6051`
`= (x^3)^2017 + (y^3)^2017`
`= (x^2017 + y^2017)(x^4034 - x^2017 . y^2017 + y^4034)`
`= 2017 xx (4034 - (2017.2015)/2)`
`= 2017 xx ((8068 - 2017 . 2015)/2)`
`= 2017 xx (2017 xx 4 - 2017 xx 2015)/2`
`= 2017 xx (2017 xx - 2011)/2`
`= (-2017^2 . 2011)/2`.
