Question 62610: Hi, ive been asked to answer the following logarithm questions, with great difficulty, there doesnt seem any decent books out there, im just wondering if you could possibly help.
1) 3log(x-2) + 1/2log(x) ( that is half log(x) )
and
2) log(3xy) - log(x)
there is no "already answered questions" and i would be most gratefull of the answer or idea for the answer.
There is also another question which i would like your opinion and solution on,
it is
1) (5+j3)(3-j)-(3+j)
I have had many attempts at this coming up with such answers as
12 + j2 and 15 + j3 , am i on the right lines of thinking or completely wrong.
I am looking forward to you results and opinions which i will highly regard.
Thank you very much for your time.
regards
pete

Question 63947: Thank you for helping me with the solution to the following problem. Our solutions do not seem to be going in the same direction would you please assist as to what I am doing wrong. This is as far as I could get with the problem.
Problem: 3log(X^2)-4log(X^2)+log(2X^3):
3log(X^2)-4log(X^2)+log(2X^3):
log((X^2)^3)-log((X^2)4)+log(2X^3)
log(X^6)-log(X^8)+log(2X^3)
log(X^-8/X^6,2X^3)log(X^-8 I am stuck here with my completion.
