can u please tell me about logs , what r they & what r their properties?

Log are the fixed numbers for a certain value

For example Log2=0.3010

whereas Log20=3.010

Properties of the logarithms:-

log(mn)=logm + logn

log(m/n)=logm - logn

logs were designed to make complicated multiplication and division problems into addition and subtraction.

log generally have two types of base:

1.Natural base (e) , also known as naperian logarithm (this name is based on logarithm method inventor john napier)

2.Common logarithm (10), base we generally use in problems.

properties:

1.if log_pq=w then p^w=q

2.log_pa + log_pb= log_p(ab)

3.log_pa^q=q*log_pa.

hope you can understand.
