1. Fire the perfect square members between (1) 30 and 40 (1) 50 and 60

1.	1. Fire the perfect square members between (1) 30 and 40 (1) 50 and 60
Answer» since 1 x 1= 12 x 2 = 43 x 3 = 94 x 4 = 165 x 5= 256 x 6 = 367 x 7 = 49 Therefore 36 is the perfect square between 30 and 40.Since 7 x 7 = 49 and 8 x 8 = 64, therefore there is no perfect square between 50 and 60 square root=30x30=900, 31x31=961; 32x32=1024, 33x33=1089; 34x34=1156; 35x35=1225; 36x36=1296; 37x37=1369; 38x38=1444; 39x39=1521; 40x40=1600 50 to 60; 50x50=2500;51×51=2601, 52x52=2704;, 53x53=2809; 54x54=2916; 55x55=3025; 56x56=3136, 57x57=3249; 58x58=3364, 59x59=3481; 60x60=3600

Answer»

since 1 x 1= 12 x 2 = 43 x 3 = 94 x 4 = 165 x 5= 256 x 6 = 367 x 7 = 49

Therefore 36 is the perfect square between 30 and 40.Since 7 x 7 = 49 and 8 x 8 = 64, therefore there is no perfect square between 50 and 60

square root=30x30=900, 31x31=961; 32x32=1024, 33x33=1089; 34x34=1156; 35x35=1225; 36x36=1296; 37x37=1369; 38x38=1444; 39x39=1521; 40x40=1600

50 to 60; 50x50=2500;51×51=2601, 52x52=2704;, 53x53=2809; 54x54=2916; 55x55=3025; 56x56=3136, 57x57=3249; 58x58=3364, 59x59=3481; 60x60=3600
