Explicație pas cu pas:
x = [2⁹⁰⁰x 2⁶⁰⁰x 2 + (2⁶)⁴⁰⁰ : 2⁸⁹⁹]² + 2³⁰⁰⁷
x = ( 2⁽⁹⁰⁰⁺⁶⁰⁰⁺¹⁾ + 2⁽⁶ˣ⁴⁰⁰⁻⁸⁹⁹⁾ )² + 2³⁰⁰⁷
x = ( 2¹⁵⁰¹ + 2⁽²⁴⁰⁰⁻⁸⁹⁹⁾)² + 2³⁰⁰⁷
x = ( 2¹⁵⁰¹ + 2¹⁵⁰¹)² + 2³⁰⁰⁷
x = (2¹⁵⁰¹)² x (1+1)² + 2³⁰⁰⁷
x = 2³⁰⁰²x2²+ 2³⁰⁰⁷
x = 2³⁰⁰⁴ + 2³⁰⁰⁷
x = 2³⁰⁰⁴x( 1+2³)
x = 2⁽²ˣ¹⁵⁰²⁾x9
______________________________________
y = 5 x ( 3²⁰⁰² - 3²⁰⁰¹ - 9¹⁰⁰⁰)
y = 5 x ( 3²⁰⁰⁰x3² - 3²⁰⁰⁰x3¹ - 3²ˣ¹⁰⁰⁰)
y = 5 x 3²⁰⁰⁰ x ( 3² - 3 - 1 )
y = 5 x 3⁽¹⁰⁰⁰ˣ²⁾ x 5
y = (5x3¹⁰⁰⁰)² → pătrat perfect
