Question

use laws of log to combine.
log12+1/2log5-log2

Answer 1

Here are the laws, and you can apply them:
log(a)+log(b) = log(a*b)
log(a)-log(b) = log(a/b)
a*log(b) = log(b^a)

Answer 2

It decomposes to log(12 * 5^(1/2) / 2).

Answer 3

Which breaks down further to be
log(6*5^(1/2)).

Answer 4

\[\log(6 \sqrt(5))\]

Answer 5

okay thanks, I did decompose it to log 12*5^1/2)/2 but i didn't break it down, i understand my fault
