Find the distance between d(P1,p2) between the points P1 and P2
P1= (1,5), P2 = (6, 6)
and i also need help with this problem
x 8
____  ____
x^264 64x^2

For the first problem,
Distance = sqrt[(y2y1)^2 + (x2x2)^2]
= sqrt[(1)^2 + 7^2] = sqrt 50 = 7.071..
Your second problem did not print out in a way that makes sense. I assume you meant
x/(x^264) 8/(64x^2)
= x/(x^264) + 8/(x^264)
= (x+8)/[(x+8)*(x8)]
= 1/(x8)
