Log vs ln? I'll explain...
MEDAL

Answer 1

\[\log _{6}10\] = log10/log6 = ln(10)/ln(6) ?

Answer 2

it is the same because of the change of base formula

Answer 3

Is there a proof or something?

Answer 4

you can use either one

Answer 5

it is the change of base formula it doesn't matter what log you use
\[\log_b(x)=\frac{\log_a(x)}{\log_a(b)}\] for \(a=10,a=e,a=17,a=\pi,...\)

Answer 6

I guess I don't fundamentally understand what a proof is then.
