Question

ab+ba: a+b=
va rog ajutati-ma​

Answer 1

Răspuns:

(ab+ba):(a+b)

(10a+b+10b+a) / (a+b) =  

( 11a+11b) / (a+b)=  

11(a+b) / (a+b)=11

Answer 2

Răspuns: $\red{\boxed{\bf \Big(\overline{ab}+\overline{ba}\Big):\Big(a+b\Big)=\bf 11}}$

Explicație pas cu pas:

$\bf \Big(\overline{ab}+\overline{ba}\Big):\Big(a+b\Big)=$

Descompunem in baza zece numerele si vom avea:

$\bf \Big(10a +b+10b +a\Big):\Big(a+b\Big)=$

$\bf \Big(11a +11b\Big):\Big(a+b\Big)=$

$\bf 11\cdot \Big(a +b\Big):\Big(a+b\Big)=$

$\red{\boxed{~\bf 11~}}$
