Enginpasa1,
Look if u go with the stmt-1, u = 16 i.e. v^4 = 16. Here u don't know whether v = 2 or -2! So stmt-1 is not sufficient.
Now if u go with stmt-2, uv=32 so v^5 = 32 -> so v = 2. u can now get the value of u and thus u/v.
So I will go for B. Is my approach clear to u Enginpasa1?
Correct me If I am wrong


Regards,

Amitava
