[tex]1000....0 (de 50 de ori) - 1 =
[tex]1000...0(de 400deori) - 99 =
1000....0(de1000deori) - 999....9(de1000deori) =
​

Answer 1

Explicație pas cu pas:

$1\underbrace{000...000}_{de \ \ 50 \ \ de \ \ ori} - 1 = \underbrace{999...999}_{de \ \ 50 \ \ de \ \ ori}$

$1\underbrace{000...000}_{de \ \ 400 \ \ de \ \ ori} - 99 = \underbrace{999...999}_{de \ \ 398 \ \ de \ \ ori}01$

$1\underbrace{000...000}_{de \ \ 1000 \ \ de \ \ ori} - \underbrace{999...999}_{de \ \ 1000 \ \ de \ \ ori} = 1$
