Sagot:

# 2sqrt2 #

Paliwanag:

#color (asul) ((6,8,2) at (8,6,2) #

Gamitin ang # "3-dimensional" # Formula ng distansya

#color (brown) (d = sqrt ((x_2-x_1) ^ 2 + (y_2-y_1) ^ 2 + (z_2-z_1) ^ 2) #

Saan

#color (indigo) (d = "distansya" #

Kaya,

#color (indigo) (underbrace ("(6,8,2) at (8,6,2)") _ ((x_1, y_1, z_1) at (x_2, y_2, z_2)

#color (violet) (x_1 = 6, x_2 = 8 #

#color (violet) (y_1 = 8, y_2 = 6 #

#color (violet) (z_1 = 2, z_2 = 2 #

# rarrd = sqrt ((8-6) ^ 2 + (8-6) ^ 2 + (2-2) ^ 2) #

# rarrd = sqrt ((2) ^ 2 + (2) ^ 2 + (0) ^ 2) #

# rarrd = sqrt (4 + 4 + 0) #

#color (green) (rArrd = sqrt (8) = sqrt (4 * 2) = 2sqrt2 #
