Calculeaza 2la puterea 1994 - 2*( 2la puterea 1990-2la puterea 1991-2la puterea 1992)=

Answer 1

2¹⁹⁹⁴-2(2¹⁹⁹⁰-2¹⁹⁹¹-2¹⁹⁹²) = 2¹⁹⁹⁴ - 2(2¹⁹⁹⁰ - 2x2¹⁹⁹⁰ - 2²x2¹⁹⁹⁰) = 2¹⁹⁹⁴ - 2x2¹⁹⁹⁰(1-2-4)=

2¹⁹⁹⁴ - 2¹⁹⁹¹ (-5) = 2³x2¹⁹⁹¹ + 5x2¹⁹⁹¹ = 2¹⁹⁹¹(8+5) = 13x2¹⁹⁹¹

Answer 2

2¹⁹⁹⁴- 2×(2¹⁹⁹⁰- 2¹⁹⁹¹- 2¹⁹⁹²) =

2¹⁹⁹⁴ - 2×(2¹⁹⁹⁰ - 2×2¹⁹⁹⁰ - 2²×2¹⁹⁹⁰) =

2¹⁹⁹⁴ - 2×2¹⁹⁹⁰×(1 - 2 - 4)=

2¹⁹⁹⁴ - 2¹⁹⁹¹ ( - 5) =

2³×2¹⁹⁹¹ + 5×2¹⁹⁹¹ =

2¹⁹⁹¹(8+5) = 13×2¹⁹⁹¹
