bentuk sederhana 3akar 3 pangkat2x-1 = 1per27 adalah

[tex](3 \sqrt{3})^{2x - 1} = \frac{1}{27} [/tex]
[tex](3 \times {3}^{\frac{1}{2} } ) ^{2x - 1} = \frac{1}{3^{3} } [/tex]
[tex](3^{ \frac{3}{2} } )^{2x - 1} = 3^{ - 3} [/tex]
[tex]3^{3x - \frac{3}{2} } = 3^{ - 3} [/tex]
kalau mencari x =
[tex]3x - \frac{3}{2} = - 3[/tex]
[tex]3x = - 3 + \frac{3}{2} [/tex]
[tex]3x = - \frac{3}{2} [/tex]
[tex]x = \frac{ - \frac{3}{2} }{3} [/tex]
[tex]x = - \frac{1}{2} [/tex]
sorry kalau salah
