You can put this solution on YOUR website!
The answers given in options A,B,C,D and E are of the form (X,Y)
So all you have to do is replace these options in the given question and see if they satisfy
for e.g.
Option A is (1/2 ,- 3)
So substituting this in y+=+3%5Ex
-3=+3%5E%281%2F2%29
which we know is not True
so Option A is not an answer
Check option B
1%2F3+=+3%5E%28-1%29
By Law of Indices X%5E%28-1%29+=+1%2FX
So we get
1%2F3+=+1%2F3 which we know is True
So Option B is a definite answer
Can you check for the other options?
