If `a^(x), b^(x)` and `c^(x)` are in GP, then which of the following is/are true? (A) a, b, c are in GP (B) log a, log b, log c are in GP (C ) log a, log b, loc c are in AP (D) a, b, c are in APA. A and BB. A and CC. B and DD. Only A

Answer» Correct Answer - B
(i) Verify from options.
(ii) Use if a, b and c are in GP, then `b^(2) = ac`.
(iii) Substitute `a^(x), b^(x)` and `c^(x)` in the above equation and simplify.
(iv) Apply logarithm for the above result and proceed.
