Domanda
(a−2b+1)3:(a+b−5)2+(a+2b)2:(a−b)(a-2b+1)^3:(a+b-5)^2+(a+2b)^2:(a-b)(a−2b+1)3:(a+b−5)2+(a+2b)2:(a−b) per a=8a=8a=8 e b=2b=2b=2.
Soluzione
(8−2⋅2+1)3:(8+2−5)2+(8+2⋅2)2:(8−2)(8-2\cdot2+1)^3:(8+2-5)^2+(8+2\cdot2)^2:(8-2)(8−2⋅2+1)3:(8+2−5)2+(8+2⋅2)2:(8−2) === (8−4+1)3:52+(8+4)2:6(8-4+1)^3:5^2+(8+4)^2:6(8−4+1)3:52+(8+4)2:6 === 53:52+122:65^3:5^2+12^2:653:52+122:6 === 53−2+144:65^{3-2}+144:653−2+144:6 === 5+245+245+24 === 292929
