I posted this problem the other day and someone answered it but when I checked my book I realized that I wrote the problem wrong. This morning when I posted I had put the wrong answer. The answer is suppose to be 1/8 but I don't understand how to solve the problem. Help would be greatly appreciated.
(1/4)^2/(1/23/4)+ 3/2^3 (It's all one equation)

First of all, it is not an equation, since it does not have an equal sign. Second, I think you wanted the sequence to be like this, so it is not just the 2 that is cubed:
(1/4)^2/(1/23/4)+ (3/2)^3
(3/2)^3 = 3/2 * 3/2 * 3/2 = 27/8
(1/4)^2 = 1/4 * 1/4 = 1/16
1/2  3/4 = 1/4
(1/16)/(1/4) = (1/16) * 4 = 4/16 = 1/4 = 2/8
2/8 + 27/8 = 25/8 = 3 1/8
I hope this breaks it down well enough for you to understand.
