i'm wondering if i can get errata for destroyer book...i think they have a lot of errors!!! which wasting my time a lot to figure out the right answer and explanation
for example..in math book p. 138 Q.38,
logb28-logb7x = logb8... what is the x?
isn't it 1/2?
logb(28/7x)=logb8
28=8* 7x = 56x, so x=28/56 = 1/2 so answer is a (1/2) but the book said D is the answer with strange explanation which is not for this problem
