Answer: (3) 0

Explanation:-
(p-1 q2/p3q-2)1/3/(p-6 q-3/p-2 q3)1/3 = pa qb
(p-1-3q2 + 2)1/3/(p-6 + 2q-3 – 3)1/3 = pa qb
(p­-4q4/p-4q-6)1/3 = paqb
(p-4 + 4q4 + 6)1/3 = paqb
(p0q10)1/3= paqb
p0/3p10/3 = pa qb
p0q10/3 = pa qb
Then, a = 0  & b = 10/3
Now, a/b = 0/(10/3)
a/b = 0

Then, the value of a/b ia 0.

Hence, the answer is (3) 0.
