    ok so one of them says that when you have log(a/b), it is the same as log(a)-log(b) ... you can apply that hear :)

    Is it log(3.8)-log(5)?

    @Hero Hmm... no. If so, that'd be weird. I don't think my Precal/Trig online course would repeat problems. Maybe it was something similar?

    actually, no. the question has a quotient/division thingy, which obviously means there's two sides to it. one is \(\large \sqrt{(3.2)(4.7)} \) and the other is \(\large 5 \) according to the law, \(\large log(\frac{a}{b})=log(a) - log(b) \) in this case, a= \(\large \sqrt{(3.2)(4.7)} \) and b = \(\large 5 \) hence: \(\large log(\frac{\sqrt{(3.2)(4.7)}}{5})=log(\sqrt{(3.2)(4.7)}) - log(5) \) =\(\large log(\sqrt{(15.04)} \ )-log(5) \)
