179 x 172 x 173 ஐ 17 ஆல் வகுத்தால் கிடைக்கும் மீதியைக் கண்டுபிடி.
பயன்படுத்தப்பட்ட சூத்திரம்:
மட்டு மதிப்பு எண்கணிதத்தின் பண்பைப் பயன்படுத்தி:
(a x b) mod m = [(a mod m) x (b mod m)] mod m
கணக்கீடு:
179 mod 17 = 179 - (17 x 10) = 179 - 170 = 9
172 mod 17 = 172 - (17 x 10) = 172 - 170 = 2
173 mod 17 = 173 - (17 x 10) = 173 - 170 = 3
⇒ 179 x 172 x 173 mod 17 = (9 x 2 x 3) mod 17
⇒ 54 mod 17 = 54 - (17 x 3) = 54 - 51 = 3
∴ சரியான விடை விருப்பம் 3.
