16 and 9
5 and 2
Since 7^2 is 49 and 8^2 is 64, And the numbers must have a square root between 7 and 8, The numbers have to be in between 49 and 64. This is because if the numbers are under 49, Its square root will be below 7. And if the numbers are above 64, Its square root will be above 8.
Yes as in the following example: (7*5)+2-1 = 36 which is a square number
Only 1.
2, 3, 7 and 8.
The first four PRIME numbers are 2,3,5,7. If you square these you get 4,9,25,49. The first four squared numbers could be 1,4,9,16
There is only one square number from 5-15: 9. This can be written as the sum of 2 and 7, which are prime numbers.
4 and 3, the squares being 16 and 9.
you find what same 2 numbers equal that number EXAMPLE: what is the square root of 49? ANSWER:7 because 7x7=49 Edit: Nearly there. 7 is the PRINCIPAL square root but there is another, which is -7. (-7)*(-7) is also 49.
The prime factors of 1666 are 2, 7, 7 and 17. From this you can see that 49, the square of 7, is a factor of 1666. 49 is the only possible square factor.
Yes because they are all prime numbers
