Use log5(2)=0.4307 and log5(3)=0.6826 to approximate the value of log5=54.

According to the example in my book I would divide 0.6826 by 0.4307 and the answer is 1.5848 but this is not one of the answers given.

My choices are:
a) 0.1370
b) 2.4785
c) 0.8820
d) 0.7488

Where did I go wrong?

Thanks

    54 = 2*3*3*3
    log 54 = log 2 + 3 log 3
    = .4307 + 3(.6826)
    = 2.4785
    Well, at least I agree with one of them !
