Answer 1

a)    

[(-11)³]4: (-11) ¹0 + (+3) ¹4 : [(+3)²]6 =

(-1331) : (-11) + (3)⁴ : (9)⁶ =

-121 : (-11) + 81 : 46656 =

121/11 + 81/46656 =

11 + 81/46656 =

11 + 0.00173 ≈ 11.00173

b)

-256 + 14 - (-2) + (-10)² + 441 : (+21) =

-256 + 14 + 2 + 100 + 441 : 21 =

-99 + 541 : 21 =

442 : 21 = 21
