If `a`,`b`,`c` are consecutive positive integers and `log(1+ac)=2K` then the value of `K`

If a , b , c are consecutive positive integers and log(1+a c)=2K , then the value of K is

If a , b , c are consecutive positive integers and (log(1+a c)=2K , then the value of K is logb (b) loga (c) 2 (d) 1

If a , b , c are consecutive positive integers and (log(1+a c)=2K , then the value of K is (a) logb (b) loga (c) 2 (d) 1

If a,b,c are any three consecutive integers, prove that log(1+ac)=2log b

If a,b,c are any three consecutive integers, prove that log(1+ac)=2log b

If n is a positive integer and (1+i)^(2n)=k cos(n pi/2) , then the value of k is

If a,b,c are any three consecutive integers , prove that log(1+ac)=2logb
