Let OP be the vector between O(-5,2,3) and P(3,0,-4). Therefore,


OP=(35)i+(02)j+(43)k=8i2j7k(3 - -5) \vec{i}+(0 - 2)\vec{j}+(-4 - 3)\vec{k}=8\vec{i}-2\vec{j}-7\vec{k}


Magnitude of OP is denoted by |OP|, where


|OP| = (8)2+(2)2+(7)2\sqrt{(8)^2+(-2)^2+(-7)^2} = 117=10.8167\sqrt{117}=10.8167 units
