2log(6/7)+(1/2)log(81/16)-log(27/196) – InterviewSolution

1.

2log(6/7)+(1/2)log(81/16)-log(27/196)

Answer»

Step-by-step explanation:

log(36/49)+log(9/4)-log(27/196) [m log n=log n^m] now APPLY log a +log b =log ab formula

log((36÷49)×(9÷4))-log(27/196). now apply log a - log b = log a/b formula. log((81/49)/(27/196)=log12
