If log a2 = A, log a3 = B and log a5 = C then log a0.006 expressed in terms of A, B and C is?

A. A-B-3C B. A+B-C C. B+2A+3C D. B-2A-3C E. none

If log a2 = A, log a3 = B and log a5 = C then log a0.006 expressed in terms of A, B and C is?
B-2A-3C = log a(3/(2^2*5^3) = loga0.006





so, answer is D
