EXAMPLE

640^3 + 224^4 + 80^5 = 1536^3 + 192^4 + 64^5 = 1792^3 + 128^4 + 32^5 = 6056574976 = 77824^2.

768^3 + 1024^4 + 96^5 = 2048^3 + 64^4 + 256^5 = 10240^3 + 64^4 + 128^5 = 1108118339584 = 1052672^2.

6250^3 + 1375^4 + 500^5 = 15625^3 + 250^4 + 500^5 = 31250^3 + 1375^4 + 250^5 = 35068603515625 =  5921875^2.
