Menjawab:

# 10 "unit" #

Penjelasan:

menggunakan versi 3-d dari #color (blue) "formula jarak" #

#color (merah) (bar (ul (| color (putih) (2/2) warna (hitam) (d = sqrt ((x_2-x_1) ^ 2 + (y_2-y_1) ^ 2 + (z_2-z_1)) ^ 2) warna (putih) (2/2) |))) #

dimana # (x_1, y_1, z_1), (x_2, y_2, z_2) "adalah 2 titik koordinat" #

# "2 poin di sini adalah" (-6,3,1) "dan" (2, -3,1) #

# "let" (x_1, y_1, z_1) = (- 6,3,1), (x_2, y_2, z_2) = (2, -3,1) #

# d = sqrt ((2 + 6) ^ 2 + (- 3-3) ^ 2 + (1-1) ^ 2) #

#color (white) (d) = sqrt (64 + 36 + 0) #

#color (white) (d) = sqrt100 = 10 "units" #
