abcd (in baza zece)=? abcd (in baza zece ) cd (in baza zece ) =112 r 2

Answer 1

Răspuns

Explicație pas cu pas:

abcd :cd =112 rest 2

abcd=112 · cd+2

ab00 +cd=112·cd +2

ab00=111•cd+2

ab00 = 111·(10c+d) +2

ab00=1110•c+111•d+2

=> d•1+2 =10 => d=8

ab00=1110•c+888+2

ab00=1110•c+890    /:10

ab0=111•c+89

1•c+9=10 => c=1

ab0=111+89

ab0=200

=> a=2, b=0, c=1, d=8

abcd=2018

verificare: 2018 :18=112 rest 2 (A)
