Let \(a, b, c\) be real numbers greater than 1, and \(n\) be a positive real number not equal to 1. If \(log_n(log_2a) = 1; log_n(log_2b) = 2\) and \(log_n(log_2c) = 3\) then which of the following…
Question and options
Let be real numbers greater than 1, and be a positive real number not equal to 1. If and then which of the following is true?
Answer and explanation
Correct answer: D - \((a^n+b)^n=ac\)
log2 a = n, log2 b = n^2, log2 c = n^3, so a=2^n, b=2^(n^2)=a^n, c=2^(n^3). Then (a^n+b)^n = (2b)^n = 2^n * 2^(n^3) = a*c.
