​

Answer 1

Răspuns:

Explicație pas cu pas:

c) 144 + 169– {2+3 . [-4– (5 – 9)]} • (-3) + 5 = 324

= 313 - [ 2 + 3 · ( - 4 + 4) ] · ( - 3 ) + 5 =

= 313 - ( 2 + 0 ) · ( - 3 ) + 5 =

= 313 + 6 + 5 =

= 324

Answer 2

144 + 169 - { 2 + 3 × [ - 4 - ( 5 - 9 ) ] } × ( - 3 ) + 5 =

313 - { 2 + 3 × [ - 4 - ( - 4 ) ] } × ( - 3 ) + 5 =

313 - ( 2 + 3 × 0 ) × ( - 3 ) + 5 =

313 - ( 2 + 0 ) × ( - 3 ) + 5 =

313 - 2 × ( - 3 ) + 5 =

313 - ( - 6 ) + 5 =

319 + 5 = 324
