Question 94510: I am desperate to know if I am doing this correctly. Would you please let me know how I am going? Thank you so much.
a=2, b=3, c=-4, d=-1, e=0
%28a%2Fb%29%5E2–%28c%2Fd%29%5E3
%282%2F3%29%5E2–%28-4%2F-1%29%5E3
(2/3) (2/3) - (-4/-1) (-4/-1) (-4/-1)
2/3*2/3 – 4*4*4
(2*3) (3*2)/3*3 – 64
6*6/9 – 64
36/9 - 64
4 – 64
= - 60

Subtract:
%282%2F3%29%5E2+-+%28-4%2F-1%29%5E3+=+%284%2F9%29+-+%28-64%2F-1%29 = %284%2F9%29-%28576%2F9%29+=+-%28572%2F9%29 = -63.555
