LOGARITHMS

Miscellaneous Examples Example 28: Suppose, logsx log12y a, where x y are positive numbers. If G is the geometric mean of x and y, then logs G is equal to a)va b)2a cla/2 dja Solution:

Miscellaneous Examples Example 29: logp q/s log/t be the possible value of sta a)1 b)-1 c)2 djBoth 1 and 2 log.p/st-1, then which of the following can Solution: logp q/s= logf ! logp st...) log, p/st = 1 => log, pst Combining (i) and (ii), we get > (st). =1 > st 1.

Miscellaneous Examples Example 30: If log 24 1.48 and log 54 1.56, then find log36. Solution: log 24 log (2x2x2x3) 3 log 2+log 3 1.48 log 54 = log (2x3x3x3) = log 2 + 3 log 3 1.56 By simplifying these two equations, we get 4 log2 +4 log3 3.04 i.e, 2 log2+ 2 log 3 1.52
