Question

Write the expression as a sum and/or difference of logarithms. Express powers as factors.log7(343x)

Answer 1

`\begin{gathered} \text{Given} \\ \log _7(343x) \end{gathered}`

Recall the product rule of logarithms

`\log _b(xy)=\log _b(x)+\log _b(y)`

Apply the product rule to the given and we get

`\log _7(343x)=\log _7(343)+\log _7(x)`
