A 360 degree rotation, around any point. Now sometimes you can do it with 180 degrees of rotation, but I need more information to specify.

Yes they are equivalent. You get -3 when you try solving the actual equation.
The answer is 204 square units
3^8=6,561
6,561 •3=19,683
The highest altitude of an altocumulus cloud is 19,683 feet.
You haven't shared the possible answers, so the best I can do (which is very good!) is to assume we want to change from base 4 to base 10 and then apply the change of base formula.
Given log-to-the-base-4-of (x+2), we want log-to-the-base-10 of (x+2). Following the change of base formula,
log-to-the-base-4-of (x+2)
log-to-the-base-10 of (x+2) = ------------------------------------
log-to-the-base-4-of-10
