I've always been stumped on the change of base problems because most of my students see it as the property that makes it so you can type things in a calculator.

I put this one in a review millionaire game and they really had to think about it. I gave them time, hints, eventually some got it. Then, I put a similar one c=log5 and c=log3, find log75, but it was a bonus(which I don't usually do) and only about 1/2 the kids got it. Just my results to share with you.JFairbankshttps://www.blogger.com/profile/09111997601925361204noreply@blogger.com
