Answer 1

Answer:

None of these because 125 = 5³ , 64 = 4³ , 27 = 3³ So none of these

Answer 2

Step-by-step explanation:

12 = 1

22 = 4

32 = 9

42 = 16

52 = 25

62 = 36

72 = 49

82 = 64

92 = 81

102 = 100

112 = 121

122 = 144

132 = 169

142 = 196

152 = 225

162 = 256

172 = 289

182 = 324

192 = 361

202 = 400

212 = 441

222 = 484

Hence, the perfect squares between 1 and 500 are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400, 441 and 484.
