Hello I have a question about a problem. The problem is (- 25/9)^3/2. Its multiple choice however I think they are tricking us.
A. 125/27
B. - 125/27
C. 125/3
D. Not a real number
I got A as an answer but feel that it is not a real number?

NM it is D not a real number
(- 25/9)^3/2
= [(- 25/9)^3]^(1/2)
we are taking the square root of a negative number, so
no real number.
