Question

polpak help me : u said that log(1+2+3) = log1+ log2+ log3 only in this case . my question is : can this be proved ?

Answer 1

what is log 6?

Answer 2

I'l prove it with a calculator =P

Answer 3

polpak said me that log(1+2+3) = log 6 or log1+log2+log3 , but only for the case of 1 , 2 and 3
he said that i am asking , that can it be proved

Answer 4

if its only for this case then calculation suffices as proof

Answer 5

log6=log(1*2*3) =log1+log2+log3

Answer 6

that's the proof

Answer 7

1+2+3=1*2*3

Answer 8

yes log6=log(1+2+3)

Answer 9

that is the Product rule

Answer 10

In this case or in any case dealing with log 1 you can do so
this because in the product rule expansion you will get log 1 as 0
