Menjawab:

# sqrt67 #

Penjelasan:

#warna (biru) ((2, -3,1) dan (-1,4, -2) #

Menggunakan #3# rumus jarak dimensi

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

Begitu,

#color (ungu) (x_1 = 2, x_2 = -1 #

#color (ungu) (y_1 = -3, y_2 = 4 #

#color (ungu) (z_1 = 1, z_2 = -2 #

Kemudian, # rarrd = sqrt ((- 1-2) ^ 2 + (4 - (- 3)) ^ 2 + (- 2-1) ^ 2) #

# rarrd = sqrt ((- 3) ^ 2 + (4 + 3) ^ 2 + (- 3) ^ 2) #

# rarrd = sqrt ((- 3) ^ 2 + (7) ^ 2 + (- 3) ^ 2) #

# rarrd = sqrt (9 + 49 + 9) #

#color (hijau) (rArrd = sqrt67 ~~ 8.18 #
