Why correct this inequality,

log(d/(d-1))>1/d for d≥2?

There must be a mistake in your question since d/d=1
You corrected the mistake.

multiplication comes before addition.
I see d/d-1 as [tex]\frac{d}{d} -1[/tex]log 0 = who-knows-what
 
Well, check first that this inequality is correct for d=2.
Then prove that the function log(d/(d-1)) will continue to be > than 1/d for d>2.
You could do that by analysis the derivative.

Get insight by making a plot of these functions.

Alternatively, study the function log(d/(d-1))-1/d .
Calculate its value for d=2, and analyze its behavior for d>2 .
