Problem Statement

This is a Korean CSAT mathematics numerical-answer problem. Solve it and put only the final integer value inside \boxed{}.

Problem 22 LetA(a, b) be a point in the first quadrant on the curve y= log 16(8x+ 2), and letBbe a point in the first quadrant on the curve y= 4 x−1 − 1 2 . The reflection ofAacross the liney=xlies on the lineOB, whereOis the origin, and the midpoint of segmentABhas coordinates 77 8 , 133 8  . If a×b= p q , wherepandqare coprime natural numbers, computep+q. [4 points] 9 Mathematics (Probability and Statistics)
