tolong yaa pliss dengan caranya

Jawaban di gambar :

x = -2

[tex] \frac{ {0.09}^{ \frac{1}{2}(x - 3) } }{ {0.3}^{3x + 1} } = 1 \\ 0.09 ^{ \frac{1}{2} (x - 3)} = {0.3}^{3x + 1 } \\ ( {0.3}^{2} )^{ \frac{1}{2} (x - 3)} = {0.3}^{3x + 1} \\ {0.3}^{x - 3} = {0.3}^{3x + 1} \\ \\ x - 3 = 3x + 1 \\ x - 3x = 1 +3 \\ - 2x = 4 \\ x = - \frac{4}{2} \\ x = - 2[/tex]
