`(2x-5)^2024 + (3y+4)^26 <= 0`
Vì `(2x-5)^2024 >= 0 AA x`
`(3y+4)^26 >= 0 AA x`
`=>{(2x-5=0),(3y+4=0):}`
`<=>{(x=5/2),(x=-4/3):}`
Ta thấy: (2x - 5)2024≥ 0 ∀ x ∈ R
(3y + 4)26 ≥ 0 ∀ y ∈ R
=> (2x - 5)2024 + (3y + 4)26 ≥ 0
Mặt khác: (2x - 5)2024 + (3y + 4)26 ≤ 0
Suy ra: (2x - 5)2024 + (3y + 4)26 = 0
\(\Leftrightarrow\left\{{}\begin{matrix}2x-5=0\\3y+4=0\end{matrix}\right.\) \(\Leftrightarrow\left\{{}\begin{matrix}x=\dfrac{5}{2}\\y=-\dfrac{4}{3}\end{matrix}\right.\)
Vậy...
