Question

The expanded form of log343÷125 is

Answer 1

Step-by-step explanation:

We know the logarithmic rules:

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

2 ) log aⁿ = n log

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

I hope this helps you .

Answer 2
