Need help with Logarithms :(

[Xecuter]

Hey,
I'm completely clueless as how to solve these 4 problems
Any help would be greatly appreciated.

2. log196 = m and log 56 = n
Express log(.175)^4 in terms of m and n

3. simplify ((log(base12)18)(log(base24)54))+5(log(base12)18)-(log(base24)54))

4. simplify ((log(base2)24)/(log(base96)2)) - (log(base2)192)/(log(base12)2)

Thanks!

Try this link: http://oakroadsystems.com/math/loglaws.htm

Just follow the simple rules and you'll get the answer. Remember, that log (a*b) = log(a) + log(b) and log(a/b) = log (a) - log(b).

1. 30^d=30^c+2

For 1, you would get:

1). 30^c = 3 , 30^d = 5, and 30^e = 8 ..... so 8 = 3+5 = 30^c + 30^d.

You should at least try to work them out instead of just letting others answer it. Try posting what you have here, and maybe we can point out any of the errors if there are any.
