Dear rahul given distance b/w points of intersection is 0.5 ie log5(k+4) -log5(k) =1/2 or log5(k+4)/k =1/2 or (k+4)/k =√5 k=4/(√5 -1) =√5 +1 so a=1 and b=5 a+b=6 Please feel free to post as many doubts on our discussion forum as you can.

Dear rahul
given distance b/w points of intersection is 0.5
ie log5(k+4) -log5(k) =1/2
or log5(k+4)/k =1/2
or (k+4)/k =√5
k=4/(√5 -1)
=√5 +1
so a=1 and b=5
a+b=6
