25 = 9 + 16
There are many more sets like these. This one has the smallest numbers.
8081 can be the sum of two perfect squares because its perfect squares are 41 x41+80x80=1681+6400. Answer=1681+6400
To find how many numbers from 10 to 93 have the sum of their digits equal to a perfect square, we first identify the possible perfect squares within the range of digit sums. The digit sum of a two-digit number ranges from 1 (for 10) to 18 (for 93). The perfect squares in this range are 1, 4, 9, and 16. By calculating the digit sums for each number from 10 to 93, we can determine that the numbers with digit sums equal to these perfect squares are 10-19 (sum = 1, 4, 9), and some others up to 93, yielding a total of 38 numbers.
You square each number and multiply that by the frequency with which that number appears. You then sum together these results.
The smallest three-digit square number is 100, which is (10^2). However, it cannot be expressed as the sum of two squares. The next three-digit square is 121 ((11^2)), which can be expressed as (11^2 = 10^2 + 1^2). Thus, 121 is the smallest three-digit square number that is also the sum of two squares.
Only 25 which is, 52 = 32 + 42 (25 = 9 + 16)
36 is a perfect square number.

5607 + 18 = 5625, a perfect square. The perfect square of a square root is the number you started with.
Only 25 which is, 52 = 32 + 42 (25 = 9 + 16)
The only squares of perfect squares in that range are 1, 16, and 81.

Squaring is the function used when we multiply a number by itself. The number you are multiplying is called the baseand the exponent 2 indicates you are multiplying the base by itself. base2 = base x base = square Squaring is the function used when we multiply a number by itself.
