46 : (x - 3²) - 10 = 13

46 : (x - 3²) - 10 + 10 = 13 + 10

46 : (x - 3²) = 23

46 : (x - 3²) * (x - 3²) = 23 * (x - 3²)

46 = 23 * (x - 3²)

46 : 23 = 23 * (x - 3²) : 23

2 = x - 3²

2 = x - 9

2 + 9 = x - 9 + 9

11 = x

x=11

\(46\div\left(x-3^2\right)-10=13\)

\(46\div\left(x-9\right)-10=13\)

\(46\div\left(x-9\right)=13+10\)

\(46\div\left(x-9\right)=23\)

\(x-9=46\div23\)

\(x-9=2\)

\(x=2+9\)

\(x=11\)

Vậy \(x=11\)
