logarithms rules

The rules of logarithms are as follows:
Lets study about logarithms rules.
Loga mn = loga m + logan, where ‘a’ is any positive number such that a≠1

Loga m/n= loga m - logan , and

Loga mb = b loga m

Where b is any rational number and m and n are positive number.You can apply the same rules on corresponding angles

Example Log15 = Log 5 + Log 3

Log 4/5= Log 4 – Log 5

Log64= Log 43 = 3 Log 4

Exercise1. convert into exponential form logm n = p

Options A. np = m

B. mp= n

C. pm= n

D mn=p

Correct answer B. This could also help us on perpendicular vectors
