Question

Calculeaza in doua moduri : 223×51+93×51 si 43×62-37×62

Answer 1

223×51+93×51=11373+4742=16116
 51×(223+93)=51×316=16116
 43×62-37×62=2666-2294=372
62×(43-37)=62×6=372

Answer 2

a)223x51+93x51=
=11373+4743=
=16116.(modul 1);


223x51+93x51=
=51x(223+93)=
=51x316=
=16116.(modul 2).


b)43x62-37x62=
=2666-2294=
=372.(modul 1);


43x62-37x62=
=62x(43-37)=
=62x6=
=372.(modul2).
