Suppose a,b,c gt 1 and n in N, n ge 2 . If log_(a)(n),log_(b)(n),log_(c )(n) are in A.P., then log_(a)b+log_(c )b =

If a,b,c are in G.P.,then prove that log a^(n),log b^(n),log c^(n)quad are in A.P.

Let n be a positive integer such that log_2 log _2 log_2 log_2 log_2 (n) lt 0 lt log_2 log_2 log_2(n) . Let l be the number of digits in the binary expansion of n. Then the minimum and the maximum possible values of l are

The value of log_(b)a+log_(b^(2))a^(2) + log_(b^(3))a^(3) + ... + log_(b^(n))a^(n)
