Question

What is the value of the expression? ( 5/2 ) ^2 +3/4 ^3

Answer 1

5/2 ^2 =  6 1/4 = 6.25

3/4^3 =  27/64 = 0.4201875

6 1/4 + 27/64 = 6 43/64  (mixed number)

6.25 +0.421875 = 6.671875 (decimal)

 not sure what format you need, since the question was in fraction form, I think you need to answer using a mixed number though.
