Answer 1

Respuesta:

322

Explicación paso a paso:

Fórmulas :

( a+b )² = a²+b²+2ab

( a+b )³ = a³+b³+3ab ( a+b )

-------

x + x⁻¹ = 3

x + 1/x = 3

( x + 1/x )² = (3)²

x²+( 1/x )²+2( x )( 1/x ) = 9

x²+1/x² +2 = 9

x²+1/x² = 7

( x²+1/x² )³ = ( 7 )³

( x² )³+( 1/x² )³+3( x² )( 1/x² )( x²+1/x² ) = 343

x⁶ + 1/x⁶ + 3( 7 ) = 343

x⁶ + 1/x⁶ = 343 - 21

x⁶ + 1/x⁶ = 322

x⁶ + x⁻⁶ = 322
