Question

te ajută am nevoie acuma vă rog frumos​

Answer 1

2¹ = 2

2² = 4

2³ = 8

2⁴ = 16

2⁵ = 32 -> U ( 2⁵) = 2

2⁶ = 64 -> U (2⁶) = 4

.....

U(2¹⁹¹⁸)

1918 : 4 = 479 r 2 -> U(2¹⁹¹⁸) = 4

U(2¹⁸⁵⁹)

1859 : 4 = 464 r 3 -> U(2¹⁸⁵⁹) = 8

U(2¹⁹⁸⁹)

1989 : 4 = 497 r 1 -> U(2¹⁹⁸⁹) = 2

U(2¹⁰⁷)

107 : 4 = 26 r 3 -> U(2¹⁰⁷) = 8

U(2¹⁰⁰)

100 : 4 = 25 -> U(2¹⁰⁰) = 6

U(2⁷²¹)

721 : 4 = 180 r 1 -> U(2⁷²¹) = 2
