\(35-x^2:3=32\)
\(x^2:3=35-32\)
\(x^2:3=3\)
\(x^2=3\times3\)
\(x^2=9\)
\(x^2=3^2\)
\(x=3\)
Vậy \(x=3\)
`35 - x^2 : 3 = 32`
`=> x^2 : 3 = 35-32`
`=> x^2 : 3 = 3`
`=> x^2 = 3^2`
`=> x = -3` hoặc `x = 3`
Vậy ...
Sửa lại ạ:
\(35-x^2:3=32\)
\(x^2:3=35-32\)
\(x^2:3=3\)
\(x^2=3\times3\)
\(x^2=9\)
\(x^2=3^2\)
\(x=3\) hoặc \(x=-3\)
Vậy ....
