7^-9=9
lnx=lx5+ln9
log10(1/x^2)=2
3log8x=log8(36)+log8(12)-log8(2)
log2(x-3)-log2(2x+1)=-log2(4)

Answer 1

The first has no 'x'.
The rest require YOU to show YOUR work. Go!

Answer 2

the first one is 7^-x=9

Answer 3

Yes I know the rest requires work but I don't know how to do it. Can you help me? You don't need to answer all of them I just want to learn how to do it. That's why i'm here.

You CAN'T have NO idea. Show us ANYTHING.

Answer 6

Its been a WHILE since I have done this. HELP ME!

Answer 7

Rule of logs: log(a) + log(b) = log(ab)

Using that rule, you can show us something in #2, #4,and #5.
