Use logarithmic properties to solve the following equation log3 5x+ log3 7= 4 leave your answer in fraction form please

Salsk061 [2.6K]

Explanation:

Adding logs of same base is equivalent to multiplying the arguments. You get:

$log_{3}(35x) = 4$

Use the definition of the log to turn this into an exponential function:

${3}^{4} = 35x$

$81 = 35x$

$x = \frac{81}{35}$
