Tí cậu gạch 2010;2020;2030;2040;2050 cả trên cả dưới nhé. Tớ ko biết ấn vào đâu để gạch

2000/2010 x 2010/2000 x 2020/2030 x 2030/2040 x 2040/50

x^2016> 2030

=> Ta có x khác 0; khác 1 và khác -1

=> Với mọi x khác ba số trên thì đều hợp lệ

( 98 . 7676 - 9898 . 76 ) : ( 2021. 2022 . 2023 ... 2030 )

= ( 98 . 76 . 101 - 98 . 101 . 76 ) : ( 2021 . 2022 . 2023 ... 2030 )

= 0 : ( 2021 . 2022 . 2023... 2030 )

= 0.
