Distance between $(-10,-2,2) and (-1,1,3)$ is $sqrt 91$ unit

The distance between two points $P(x_1,y_1,z_1)$ and

$Q(x_2,y_2,z_2)$ in xyz-space is given by formula,

$D=sqrt((x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2$

Here $P=(-10,-2,2) and Q=(-1,1,3)$

$D(P,Q)=sqrt((-1+10)^2+(1+2)^2+(3-2)^2$ or

$D(P,Q)=sqrt(81+9+1)= sqrt 91$ unit

Distance between $(-10,-2,2) and (-1,1,3)$ is $sqrt 91$ unit [Ans]

What is the distance between (–10, –2, 2) (–10, –2, 2) and (–1, 1, 3) (–1, 1, 3) ?
