Let x, y, n be integers. I explore x and y for 1 through 15. I use an HP 32Sii to help me with the calculations.
x^2 + y^2 = n^3
2^2 + 2^2 = 2^3
2^2 + 11^2 = 5^3
5^2 + 10^2 = 5^3
Program:
LBL A

x^3 + y^3 = n^2
1^3 + 2^3 = 3^2
2^3 + 2^3 = 4^2
8^3 + 4^3 = 24^2
8^3 + 8^3 = 32^2

10^2  6^2 = 4^3

If you want to find more integer triplets, happy exploring!
To all the dads out there  Happy Father's Day! To my dad, I am so proud of you!
Until next time,
