Question

aflati nr ab in care a+b=8
am test repede dau coroana ​

Answer 1

Explicație pas cu pas:

a diferit de 0 (1 , ....,8)

b = (0 , ....,7)

daca a = 1, 1 +b = 8, b = 8-1, b = 7

ab = 17

daca a = 2, 2 +b = 8, b = 8-2, b = 6

ab = 26

si tot asa...

sper ca acum te descurci

daca a = 3, 3+b = 8, b = 8-3, b = 5

ab = 35

daca a = 4, 4 +b = 8, b = 8-4, b = 4

ab = 44

daca a = 5, 5+b = 8, b = 8-5, b = 3

ab = 53

daca a = 6, 6 +b = 8, b = 8-6 b = 2

ab = 62

daca a = 7, 7 +b = 8, b = 8-7, b = 1

ab = 71

daca a = 8, 8 +b = 8, b = 8-8, b = 0

ab = 80
