Answer 1

Answer:

3log(7/5)

Step-by-step explanation:

log 343/125

log(7)^3 /(5)^3

log(7/5)^3

3log (7/5)

Answer 2

Question:-

Expand log 343/125

Answer:-

As you know ,

$log_{a} \frac{x}{y} = log_{a}x + log_{a}y$

So,

$log \: \frac{343}{125}$

$= > log \: 343 - log \: 125$

$= > log {7}^{3} - log \: {5}^{3}$

$= > 3log \: - \: log5$

$= > (since \: log_{a} {x}^{n} = n log_{a}x)$

$= > log \frac{343}{125}$

☘︎ 3 ( log 7 - log 5 ) ☘︎
