25 and 54
They cannot be integers or whole numbers; but they can be numbers with decimals. There are many possibilities; if the numbers are the same, then that is the square root of 10000000 which is 3162.277666...repeating. Those same numbers multiplied together = 10000000. If numbers are different, there are other combinations, all involving decimals
293 is already prime. Those numbers don't exist.
Those are all square numbers.
The sum of two numbers is those two numbers multiplied together. For instance, the sum of 4 and 5 is 20.
You find the same two numbers that make the number, then you use one of those numbers for your square root.

Those numbers are called factors. A pair of those is called a factor pair.
293 is already prime. Those numbers don't exist.
Those are all square numbers.
2009=7x7x41 and those are all primes.
Square numbers are the products of numbers that have been multiplied by themselves like 2 x 2 = 4, or 9 X 9 = 81. The squares here are 4 and 81.Numbers that can be made by multiplying another number my itself, like 12 x 12 = 144. So 144 is a square number.By convention and probably also by definition, square numbers and square roots (the numbers multiplied by themselves) are always whole numbers, integers with no factional or decimal parts.A square number is the result of any non-zero integer multiplied by itself.9 is a square number because 3 x 3 = 9.5 is not a square number because there isn't an integer that can be multiplied by itself to make 5.
