question 3

Multiple Choice

Determine which $x$ -value below is a solution of the equation $\log _ { 7 } \left( \frac { 5 } { 3 } x \right) = 3$ .
$$x = \frac { 21 } { 125 } , x = \frac { 1029 } { 5 } , x = \frac { 189 } { 5 } , x = 21 , x = 15$$

• A) \(x = \frac { 21 } { 125 }\)
• B) \(x = \frac { 1029 } { 5 }\)
• C) \(x = \frac { 189 } { 5 }\)
• D) \(x = 21\)
• E) \(x = 15\)
