giải giúp mình mấy hệ pt sau nhé
1.\(\left\{{}\begin{matrix}2x^3+y\left(x+10=4x^2\right)\\5x^4-4x^6=y^2\end{matrix}\right.\)
2.\(\left\{{}\begin{matrix}x-\sqrt{y+1}=\dfrac{5}{2}\\y+\left(x-3\right)\sqrt{x+1}=-\dfrac{3}{4}\end{matrix}\right.\)
3.\(\left\{{}\begin{matrix}x^2+y^2=2\\\left(x+y\right)\left(4-x^2y^2-2xy\right)=2y^2,2y^3,2y^5\end{matrix}\right.\)trong 3 cái đó có 1 cái nha
4.\(\left\{{}\begin{matrix}x^3-8x=y^3+2y\\x^2-3y^2=6\end{matrix}\right.\)
mọi người giúp nhanh nha
thanks nhiều
