Answer:

x = 1/3

Step-by-step explanation:

[tex] = > log_{(3x + 4)}125 = 3[/tex]

[tex] = > {(3x + 4)}^{3} = 125 \: ( \because \: log_{a}b = x = > {a}^{x} = b)[/tex]

[tex] = > 3x + 4 = \sqrt[3]{125} = 5[/tex]

[tex] = > 3x = 5 - 4 = 1[/tex]

[tex] \therefore \: \: x = \frac{1}{3} [/tex]

Hope you've understood the solution.
