निम्न संख्याओं का वर्ग ज्ञात कीजिए:
(i) 32 (ii) 35 (iii) 86 (iv) 93 (v) 71 (vi) 46
(i) (32)2 = (30 + 2)2
= 302 + 2(30)(2)+(2)2
= 900 + 120 + 4
= 1024
(i) (35)2 = (30 + 5)2
= 302 + 2(30)(5)+(5)2
= 900 + 300 + 25
= 1225
(iii) (86)2 = (80 + 6)2
= (80)2 + 2(80)(6)+(6)2
= 6400 + 960 + 9
= 8649
(iv) (93)2 = (90 + 3)2
= (90)2 + 2(90)(3)+(3)2
= 8100 + 540 + 9
= 8649
(v) (71)2 = (70 + 1)2
= (70)2 + 2(70)(1)+(1)2
= 4900 + 140 + 1
= 5041
(vi) (46)2 = (40 + 6)2
= (40)2 + 2(40)(6)+(6)2
= 1600 + 480 + 36
= 2116
