Question

Log3 5 + Log3 7 + Log3 9 = log3 x
​

Answer 1

Step-by-step explanation:

$given \: that \\ log_{3}(5) + log_{3}(7) + log_{3}(9) = log_{3}(x) \\ = > log_{3}(5 + 7 + 9) = log_{3}(x) \\ since \: log_{a}(x) + log_{a}(y) = log_{a}(xy) \\ = > log_{3}(21) = log_{3}(x) \\ we \: know \: that \: \\ = > 21 = x \\ therefore \: x = 21 \\ the \: value \: of \: \: x \: is \: 21$
