Explicație pas cu pas:
a) - 3² + ( - 5 ) × 3 + ( 0 - 1 )¹⁶ + ( - 2² )² = - 7
= - 9 - 15 + ( - 1)¹⁶ + ( - 4 )² =
= - 24 + 1 + 16 =
= - 7

b)
15 + ( - 2 )³- ( - 4 + 3 )⁷⁶ x ( - 3 )² = - 2
= 15 - 8 - ( - 1 )⁷⁶ x 9 =
= 7 - 1 x 9 =
= 7 - 9 =
= - 2

c)
- 1¹⁰ + ( - 2) x [ ( 2 - 3 ) + 8 - ( - 6 + 5) ] : ( - 2 )³ = 1
= - 1 + ( - 2 ) x ( - 1 + 8 + 1 ) : (- 8 ) =
= - 1 + ( - 2 ) x 8 : ( - 8 ) =
= - 1 + ( - 16 ) : ( - 8 ) =
= - 1 + 2 =
= 1
