Question

Anyone know how to simplify a log?
REALLY NEED HELP, FINAL EXAM TOMORROW

Answer 1

3log(2x)-1/2logx^4

Answer 2

Tons of ways to simplify it... it depends on the particular problem. Logs can be expanded in several different ways.

1) log(mn) = log(m) + log(n)

2) log(m/n) = log(m) – log(n)

3) log(mn) = n · log(m)

Give it a try with these in mind ^^^

Answer 3

Here's a link that shows it better since it doens't show up on this website very well http://www.purplemath.com/modules/logrules.htm

Answer 4

well the answer is log(8x^3)-logx^2 but I don't remember how I got it

Answer 5

Is the answer you got correct? I got a different result...

Answer 6

-1/2 * logx^4 becomes -2*logx

Answer 7

then 3log(2x) becomes 3*(log2 + logx)

Answer 8

putting the two together you get 3log(2x) - .5logx^4 = 3log2 + 3logx - 2logx

Answer 9

how did you do it?

Answer 10

which equals 3log2 + logx

Answer 11

how did you change them?

Answer 12

Ok let me draw it out

Answer 13

using rule #3 in the link i posted
