Question

log12 81 = p, then 3[(4-p)/(4+p)] is equal to

log4 16
log6 8
log6 16
log2 8

Answer 1

Answer:

The correct option is B.

Explanation:

log12 81 = p

log12 34 = p

4 log12 3 = p

Now,

4 - p = 4 - 4 log12 3

= 4(1 - log12 3)

= 4(log12 12 - log12 3)

= 4 log 4

Similarly,

4 + p = 4 log 36

3[(4-p)/(4+p)] = 3 log 4 / log 36

= 3 log36 4

= log6 8
