=> 288 : (x-3)^2 = 50 - 8.6 = 2
=> (x-3)^2 = 288 : 2 = 144
=> x-3=-12 hoặc x-3=12
=> x=-9 hoặc x=15
Vậy ........
Tk mk nha
\(=48+288:(x-3)^2=50\)
\(=288:(x-3)^2=50-48\)
\(=288:(x-3)^2=2\)
\(=(x-3)^2=288:2\)
\((x-3)^2=144\)
\((x-3)^2=12^2\)
\(x-3=12\)
\(x=12+3=15\)
Cảm ơn bn Nguyễn Anh Quân nhìu!! ^^
Cám ơn bn Huỳnh Quang Sang nha!! ^^
\(8.6+288:\left(x-3\right)^2=50\)
\(48+288:\left(x-3\right)^2=50\)
\(288:\left(x-3\right)^2=50-48\)
\(288:\left(x-3\right)^2=2\)
\(\left(x-3\right)^2=288:2\)
\(x^2-9=144\)
\(x^2=144+9\)
\(x^2=153\)
\(x\approx12\)
\(8.6+288:\left(x-3\right)^2=50\)
\(\Rightarrow48+288:\left(x-3\right)^2=50\)
\(\Rightarrow288:\left(x-3\right)^2=2\)
\(\Rightarrow\left(x-3\right)^2=144\)
\(\Rightarrow\orbr{\begin{cases}x-3=\sqrt{144}\\x-3=-\sqrt{144}\end{cases}\Rightarrow\orbr{\begin{cases}x-3=12\\x-3=-12\end{cases}}\Rightarrow\orbr{\begin{cases}x=15\\x=-9\end{cases}}}\)
Vậy ...
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 = 288 : 2
=> (x - 3)2 = 144
=> (x - 3)2 = 122
=> x - 3 = 12
=> x = 12 + 3
=> x = 15
Vậy x = 15
Mơn bn Sakuraba Laura đã giúp mk nha!^^
