k cho mình nhé.

8.6+ 288: ( x -3)\(^2\)= 503

48+ 288: (x-3)\(^2\)= 50

      288: (x-3)\(^2\)= 50-48

      288: (x-3)\(^2\)= 2

              (x-3)\(^2\)= 288:2

              (x-3)\(^2\)= 144

              (x-3)\(^2\)= 12\(^2\)

=>x- 3= 12=> x= 12+ 3x= 15

48+288:(x-3)^2=50

288:(x-3)^2=50-48

288:(x-3)^2=2

(x-3)^2=288:2

(x-3)^2=144

(x-3)^2=12^2    or      (x-3)^2=(-12)^2

=>x-3=12                    =>x-3=-12

 x=15                               x=9

\(8.6+288:\left(x-3\right)^2=50\)

\(\Leftrightarrow48+288:\left(x-3\right)^2=50\Leftrightarrow288:\left(x-3\right)^2=2\)

\(\Leftrightarrow\left(x-3\right)^2=144\Leftrightarrow\left(x-3\right)^2=\left(\pm12\right)^2\)

TH1 : \(x-3=12\Leftrightarrow x=15\)

TH2 : \(x-3=-12\Leftrightarrow x=-9\)

Biến đổi được: (x-3)²=144=12²=(-12)²

\(\Leftrightarrow\)\(\left[{}\begin{matrix}x-3=12\\x-3=-12\end{matrix}\right.\) \(\Leftrightarrow\left[{}\begin{matrix}x=15\\x=-9\end{matrix}\right.\)

8*6+288/(x-3)^2=50

48+288/(x-3)^2=50

288/(x-3)^2=50-48

288/(x-3)^2=2

(x-3)^2=2*288=576=24^2

=>x-3=24

x=24+3

x=27

Vậy x=27

toi hoc gioi toan tinh lai thu xem 27 la x hay sao minh tinh miet ko ra
