Substitute each of the small letters by a different base ten digit from 1 to 9, with a<= b<=c<=d, to satisfy this equation.

a2 + b2 + c2 + d2 = e2

That wasn't that hard... just trial and error
22 + 42 + 52 + 62 = 92

This is a fascinating mathematical puzzle that involves finding a combination of four different digits that satisfy a specific equation. The equation, a2 + b2 + c2 + d2 = e2, is known as the "sum of four squares" equation, and it has been studied by mathematicians for centuries.

To solve this puzzle, we must first understand the properties of the equation and how it relates to the digits we need to substitute. The equation represents a Pythagorean triple, where a, b, c, and d are the sides of a right triangle, and e is the hypotenuse. This means that the four digits we substitute must form a right triangle when arranged in a specific way.

Next, we must consider the constraints given in the puzzle, namely that a<= b<=c<=d and that each digit must be different. These constraints limit the possible combinations of digits that we can use to solve the equation.

I would approach this puzzle by using a systematic and logical method, such as trial and error or a mathematical algorithm, to test different combinations of digits and see if they satisfy the equation. I would also use my knowledge of number theory and properties of Pythagorean triples to guide my search for a solution.

Overall, this puzzle is a great way to exercise our mathematical skills and explore the relationships between numbers and equations. It also highlights the beauty and complexity of mathematics and the endless possibilities for problem-solving and discovery.
