What does it mean by this?

>>8536615
It means that [math]log_3(x)[/math] is not defined for any x <0, so the inequality is not strictly true.

>>8536629
undefined =/= undefined?????????????

>>8536615
logs of negatives are complex

https://www.wolframalpha.com/input/?i=log(3,-4),+log(1%2F3,+-1%2F4)

consider ln(-2)/ln(2) gives you (ln2+ipi)/ln2 ln(1/-2)/(ln(1/3) gives -(ln2+ipi)/ln2

i mean to say that it holds true
lnx=-ln(1/x) for all x, real or complex

It doesn't mean. It computes. It's a computer ya dingus.
