If log303 = a, log305 = b, then log308 =?	Choose the correct choice from the following:
A) 3(1 - a - b) B) (a - b + 1) C) (1 - a - b) D) (a - b + 1) E) none of these
a + b = log3015 = log30(30/2) = 1- log302   =&gt; log302 = (1 - a - b)   Therefore, log308 = 3(1 - a - b).   3(1 - a - b)NSWER:3(1 - a - b)
<result>A</result>
If log303 = a, log305 = b, then log308 =?
