Question

Evaluate log3 5 + log3 7 + log3 9 = log3 x
​

Answer 1

Answer:

log3 5 + log3 7 + log 3 9 = log3 x

so by using the property log a + log b = log ab

there for

log3 ( 5×7×9) = log3 x

log3 (315) = log3 x

so

x = 315

nb: this problem is solved in an aspect of log to the base 3 not as log cube or log multiplied by 3
