**Steve**, Wednesday, April 17, 2013 at 5:15pmlog(a^b) = b log(a)

log(ab) = log(a) + log(b)

since 1/b = b^-1,

log(a/b) = log(a) - log(b)

since √a = a^(1/2),

log √a = 1/2 log a

log x^4y^7/4 = 4logx + 7logy - log4

so you should be able to do the other

if these problems involve logs base 4, that doesn't matter. The rules of logs are independent of the base.
