(-1)2=1 all squared numbers turn out positive and 12=1 (-1)2=1 all squared numbers turn out positive and 12=1
When you square a number, the final digit is the final digit of the 'one's' number squared. Since the only single digit numbers squared which ends in 6 are 4 and 6, the answer is either 4 or 6 (a calculator tells me it is 6) 0 squared is 0. All numbers ending in 0 when squared will end in 0. 1 squared is 1. All numbers ending in 1 when squared will also end in 1. 2 squared is 4. All numbers ending in 2 when squared will end in 4. 3 squared is 9. All numbers ending in 3 when squared will end in 9. 4 squared is 16. All numbers ending in 4 when squared will end in 6. 5 squared is 25. All numbers ending in 5 when squared will end in 5. 6 squared is 36. All numbers ending in 6 when squared will end in 6. 7 squared is 49. All numbers ending in 7 when squared will end in 9. 8 squared is 64. All numbers ending in 8 when squared will end in 4. 9 squared is 81. All numbers ending in 9 when squared will end in 1. So square numbers can only end with 0, 1, 4, 5, 6 or 9.
1, 4 and 9
1. It is not bigger than 300. It is smaller than 200 squared.
If you include the numbers on the ends, then there are 300 of them. If you don't include the '1' and the 300, then there are 298.
