Question 744908
use {{{log A/b = log( A) - log( B)}}}. .......the division rule


a. {{{log (4,11)}}}

first write {{{11}}} as {{{22/2}}}, and do so with all other problems


{{{log (4,11)= log(4, 22) - log( 4,2)}}}


b.{{{log (3,12)}}}

{{{log (3,12)= log(3, 24) - log( 3,2)}}}



c. {{{log (9,5)}}}

{{{log (9,5)= log(9, 10) - log(9,2)}}}



d.

{{{log (6,7)}}}

{{{log (6,7)= log(6, 14) - log(6,2)}}}



e. {{{log (11,21)}}}

{{{log (11,21)= log(11, 42) - log(11,2)}}}



f. {{{log (2,13)}}}

{{{log (2,13)= log(2, 26) - log(2,2)}}}
