Answer 1

Răspuns:

Explicație pas cu pas:

$\bf [(14+3\cdot6-4):4+3]:2 +8=$

$\bf [(14+18-4):4+3]:2 +8=$

$\bf [(32 - 4) : 4+3]:2 +8=$

$\bf (28: 4+3):2 +8=$

$\bf (7+3):2 +8=$

$\bf 10:2 +8=$

$\bf 5 +8=$

$\bf \purple{\underline{~13~}}$

                                 

$\bf [(5^2-3^2):(3^2-3^0)+5\cdot2-3] : 3+3\cdot2=$

$\bf [(25-9):(9-1)+10-3] : 3+6 =$

$\bf [(16:8)+10-3] : 3+6 =$

$\bf (2+10-3) : 3+6 =$

$\bf 9 : 3+6 =$

$\bf 3+6 =\red{\underline{~9~}}$
