Question

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. The answer is suppose to be 43/128 and I can't get it. Thanks

(1/4)^2/(1/2-3/4)+ 3/2^3

Answer 1

I think it is not correct yet. I can't make any way for those numbers to equal 43/128

Answer 2

I'm so sorry it's suppose to be 1/8
