p = 106
q = 105
r = 104
वापरलेले सूत्र:
p2 + q2 + r2 - pq - qr - rp
गणना:
p2 + q2 + r2 - pq - qr - rp = 1062 + 1052 + 1042 - 106 × 105 - 105 × 104 - 104 × 106
⇒ 1062 = 11236
⇒ 1052 = 11025
⇒ 1042 = 10816
⇒ 106 × 105 = 11130
⇒ 105 × 104 = 10920
⇒ 104 × 106 = 11024
⇒ 11236 + 11025 + 10816 - 11130 - 10920 - 11024
⇒ 33077 - 33074
