$distance= \sqrt{51}$ $"distance="sqrt51$

Explanation:

$P_{1} = (8, 3, 4) P_{2} = (1, 2, 5)$ $P_1=(8,3,4)" "P_2=(1,2,5)$
$Delta x=1-8=-7$
$Delta y=2-3=-1$
$Delta z=5-4=1$
$"distance="sqrt(Delta x^2+ Delta y^2 + Delta z^2)$
$"distance:"sqrt((-7)^2+(-1)^2+1^2)$
$"distance="sqrt(49+1+1)$
$"distance="sqrt51$
