Which expression has a value that is less than the base of that expression?
(in this picture it is a screenshot, so look at question number 1, ok? )

Whenever you have positive exponents, bases above 1 will be greater after the exponent and bases between 0 and 1 will be less after the exponent. Based on this, your answer would be B) (5/6)^2, as 5/6 is less than one but greater than 0.

Volume = the base times the height. i’m not going your work for you, but this is all you need to know.
