I have a calc final tomorrow and I can't seem to figure this problem out. Please help. He gave us the answer which was 1.500, but I don't know how he got it.

Let logb A = 5 and logb B = -2. Find logb 2√AB.

$\displaystyle \sqrt{a} = a^{\frac{1}{2}}$

I'm stuck on logb (2). When I add it to the rest of the problem it came out to be a completely different answer.
