Division Law
once the bases are the same powers should be subtracted
107 / 105=
102=100
Evaluate log28=
3
•The multiplication of two logarithmic values is equal to the addition of their individual logarithms.
Product Rule
The exponential form of log9x = 3 is
x=93
which law states that when the bases are the same the powers must be added
multiplication Law
Quotient Rule
The division of two logarithmic values is equal to the difference of each logarithm.
93=729 in log form is
log9729=3
solve for the value of x for log3 x= log3 4+ log3 7
x= 28.
