Question

me podrían ayudar con esto porfa

Answer 1

Explicación paso a paso:

1.

xxx(8) = 511

X(8)² + 8x + x = 511

64x + 9x = 511

73x = 511

x = 7

2.

3n0 = 226(13)

300 + 10n = 2(13)² + 2(13) + 6

300 + 10n = 338 + 26 + 6

300 + 10n = 370

10n = 70

n = 7

3.

583 a base 2

583 = 291(2) + 1

291 = 145(2) + 1

145 = 72(2) + 1

72 = 36(2) + 0

36 = 18(2) + 0

18 = 9(2) + 0

9 = 4(2) + 1

4 = 2(2) + 0

2 = 1(2) + 0

1001000111(2)

4.

7ab = 26(ab)

700 + ab = 26ab

700 = 25ab

28 = ab

a = 2

b = 8

E² = 4(2) + 8

E² = 16

E = 4
