Penjelasan dengan langkah-langkah:
[tex] \frac{ {5}^{x} + {5}^{ - x} }{ {5}^{x} - 3( {5}^{ - x}) } = 3[/tex]
[tex] \frac{ {5}^{x} + \frac{1}{ {5}^{x} } }{ {5}^{x} - \frac{3}{ {5}^{x} } } = 3[/tex]
[tex]misal \: \: {5}^{x} \: adalah \: \: p[/tex]
[tex] \frac{p + \frac{1}{p} }{p - \frac{3}{p} } = 3[/tex]
[tex] \frac{ \frac{ {p}^{2} + 1}{p} }{ \frac{ {p}^{2} - 3}{p} } = 3[/tex]
[tex] \frac{ {p}^{2} + 1 }{p} \times \frac{p}{ {p}^{2} - 3 } = 3[/tex]
[tex] \frac{ {p}^{2} + 1}{ {p}^{2} - 3 } = 3[/tex]
[tex] {p}^{2} + 1 = 3 {p}^{2} - 9[/tex]
[tex]1 + 9 = 3 {p}^{2} - {p}^{2} [/tex]
[tex]10 = 2 {p}^{2} [/tex]
[tex]5 = {p}^{2} [/tex]
[tex] \sqrt{5} = p[/tex]
Jadi :
[tex]p = \sqrt{5} [/tex]
[tex] {5}^{x} = {5}^{ \frac{1}{2} } [/tex]
[tex]x = \frac{1}{2} [/tex]
