I think the answer is E

st.1

-3^2 = 9
2^-3 = 1/8

3^2 = 9
2^3 = 8
Not sufficient

st.2

-3^2 = 9
2^-3 = 1/8

3^2 = 9
2^3 = 8
Not sufficient

Both statements together are not sufficient as well.

Please correct me if I am wrong.

E - the stem is basically asking if n>=0

A - insufficient, n could be -ve and m +ve
B - insufficient - just tells us that m is positive
C - insufficient
