Question

What is the distance between P(–2, 1, 3) and point Q(–1, 4, –2)?

Answer 1

$\sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} + {(z2 - z1)}^{2} } \\ = \sqrt{ {( - 1 + 2)}^{2} + {(4 - 1)}^{2} + {( - 2 - 3)}^{2} } \\ = \sqrt{1 + 9 + 25} \\ = \sqrt{35} .$

may be this answer is correct ..

hope this will helps you.
