Question

13 la baza 7 plus 42 la baza 6 Plus 32 la baza 5​

Answer 1

Răspuns:

$13 {}^{(7)} = 1 \times 7 {}^{0} + 3 \times {7}^{1} \\ = 1 \times 1 + 3 \times 7 \\ 1 + 21 = 22$

$42 {}^{(6)} = 4 \times {6}^{0} + 2 \times {6}^{1} \\ = 4 \times 1 + 2 \times 6 \\ = 4 + 12 = 16$

$32 {}^{(5)} = 3 \times 5 {}^{0} + 2 \times 5 {}^{1} \\ = 3 \times 1 + 2 \times 5 \\ = 3 + 10 = 13$

$13 {}^{(7)} + 42 {}^{(6)} + 32 {}^{(5)} = 22 + 16 + 13 \\ = 38 + 13 = 51$
