cari himpunan penyelesaian

[tex] {3}^{x^{2} - 6x } = \frac{1}{243} \\ {3}^{ {x}^{2} - 6x} = {3}^{ - 5} \\ {x}^{2} - 6x = - 5 \\ x^{2} - 6x + 5 = 0[/tex]
kemudian pakai rumus ABC❣
[tex]x = \frac{ - ( - 6) + - \sqrt{( - 6) ^{2} - 4 \times 1 \times 5 } }{2 \times 1} \\ x = \frac{6 + - \sqrt{36 - 20} }{2} \\ x = \frac{6 + - \sqrt{16} }{2} \\ x = \frac{6 + - 4}{2} \\ x = \frac{6 + 4}{2} \\ x1 = 5 \\ x = \frac{6 - 4}{2} \\x2 = 1 [/tex]
