Are all statements that are true.
(a) log(A)/log(B)=In(A)/In(B)
(b) In log[b](N), the exponent is N.
(c)If 2log[3](81)=8, then log[3](6.561)=8
(d)log[b](N) negative when N is negative.
(e)In(x/2)=In(x)/2

only (a) is true

1) use the properties of logarithms to simplify the logarithmic expression. log base 10 (9/300) log  log 300 log 9 = 2 log 3 log 300 = log 3 + log 100 = log 3+2 I just do not know how to put these together now!

Suppose you are told that log(2)=0.3562 and log(3)=0.5646. All of them with the base of 'a'. Find: i) log(6) ii) log(9) Solutions i) log(6)= log (3)(2) = log 3 + log 2 = 0.5646 + 0.3562 = 0.9208 ii)log(9)= log 3^2 = 2 log 3 = 2 (0.5646) …
