Answer 1

Răspuns:  28

Explicație pas cu pas:

{15 x 4 + 15 x 16 - 20 x [(5^2 - 3^2 + 2^3) : 8 - 2]} : 10 =

{15 x (4 + 16) - 20 x [(25 - 9 + 8) : 8 - 2]} : 10 =

{15 x 20 - 20 x [24 : 8 - 2]} : 10 =

{15 x 20 - 20 x 1} : 10 =

{300 - 20} : 10 =

280 : 10 =

Answer 2

Răspuns: 28

Explicație pas cu pas:

$\bf \{15\cdot 4+15\cdot16-20\cdot[(5^2-3^2+2^3):8-2]\}:10 =$

$\bf \{15\cdot 4+15\cdot16-20\cdot[(25-9+8):8-2]\}:10 =$

$\bf [15\cdot 4+15\cdot16-20\cdot(24:8-2)]:10 =$

$\bf [15\cdot 4+15\cdot16-20\cdot(3-2)]:10 =$

$\bf (15\cdot 4+15\cdot16-20\cdot 1):10 =$

$\bf (60+15\cdot16-20\cdot 1):10 =$

$\bf (60+240-20):10 =$

$\bf 280:10 =$
