#s=sqrt 74#

Explanation:

#P_1->(x_1,y_1,z_1) " the point of "P_1#
#P_2->(x_2,y_2,z_2)" the point of "P_2#
#Delta x=x_2-x_1=-1+9=8#
#Delta y=y_2-y_1=4-3=1#
#Delta z=z_2-z_1=-2-1=-3#
#"s:distance between the Point of " P_1 " and "P_2"#
#s=sqrt(Delta x^2+Delta y^2+Delta z^2)#
#s=sqrt(64+1+9)#
#s=sqrt 74#
