The first 10 perfect square numbers are the squares of the first ten natural (or counting) numbers:
1² = 1
2² = 4
3² = 9
4² = 16
5² = 25
6² = 36
7² = 49
8² = 64
9² = 81
10² = 100
Although 0² = 0, zero can also be obtained by any number (not just 0) times zero, eg 2 × 0 = 0, so I've not included it in the list.
no, 10 is not a perfect square. in order for a number to be a perfect square, you have to see if the numbers that are multiplied to get it are the same. for example: 2x2=4; 4 is a perfect square. 12x12=144; 144 is also a perfect square 5x2=10 or 10x1=10. 10 isn't a perfect square because 5 and 2, and 10 and 1, are different numbers.

16 of them.
Numbers whose digits add to a perfect square between 10 and 87 are: 10 = 1 + 0 = 1 = 12 13 = 1 + 3 = 4 = 22 18 = 1 + 8 = 9 = 32 22 = 2 + 2 = 4 = 22 27 = 2 + 7 = 9 = 32 31 = 3 + 1 = 4 = 22 36 = 3 + 6 = 9 = 32 40 = 4 + 0 = 4 = 22 45 = 4 + 5 = 9 = 32 54 = 5 + 4 = 9 = 32 63 = 6 + 3 = 9 = 32 72 = 7 + 2 = 9 = 32 81 = 8 + 1 = 9 = 32 This is a total of 13 numbers.* * * * *And also79 = 7 + 9 = 16 = 42So a total of 14 numbers.
√2000 ≅ 44.7 √3000 ≅ 54.8 The squares of 45 to 54 lie within the range 2000 to 3000. There are thus 10 perfect square numbers between 2000 and 3000.

perfect square numbers are 16 and 25
There are 17 such numbers.
There are 11 numbers from 10 to 20 if we include 10 and 20. Of those, only 16 is a perfect square. So the probability if 1/11 or .09 repeating.
depends on the numbers on the spinner. if 1 thru 10, 7/10
