Answer 1

Answer:

We know the logarithmic rules:

1 ) log ( x/y ) = log x - log y

2 ) log aⁿ = n log a

***************************************

Now ,

log ( 343/125 )

= log ( 7³/5³ )

= log ( 7/5 )³

= 3 log ( 7/5 )

= 3 [ log 7 - log 5 ]

Or

= 3log 7 - 3 log 5

Step-by-step explanation:

Answer 2

As you know , log a x / y = log a x - log a y

so , log 343 / 125 = log 343 - log 125

= log 7^3 - log 5 ^3

= 3 log 7 + 3 log 5 [ since , log x n = log x ]

So , log 343 / 125 = 3 ( log 7 - log 5)
