Hi RauLiTo,
we know 1000=10³ ,
hence, log(1000) to the base 10 = 3.
Logarithms are calculated for the two bases, e and 10.
Logarithm to base e is called Natural logarithm and logarithm to base 10 is common logarithm. Go to this link for knowing more.
Logarithms help in calculating approximately quickly.
For example, by knowing what log 2(to the base 10) is, it can easily be said how large a number 2^100 would be!
If you have any specific doubts or problems, you may post here.

If 2³ = x, then log x (to the base2) is equal to 3.
However, log4^3<log 5^3,
Since 4^3 = 64 and 5^3 = 125

it seems easy but not for a beginner like me in logs !

can anyone prove that :
log4^3 > log5^3
