Explicație pas cu pas:
a)
2019⁰ + 0²⁰¹⁹ + 1²⁰¹⁹ =
1 + 0 + 1 = 2

b)
(2³ + 2 · 2⁴ + 2⁹) : (8 + 2¹² : 2³ + 2⁵) =
(2³ + 2¹⁺⁴ + 2⁹) : (2³ + 2¹²⁻³ + 2⁵) =
(2³ + 2⁵ + 2⁹) : (2³ + 2⁹ + 2⁵) = 1

c)
3⁴¹ · 9 - 3⁴⁴ + (4²⁵ : 2⁴⁹ + 1)⁰ =
3⁴¹ · 3² - 3⁴⁴ + [(2²)²⁵ : 2⁴⁹ + 1]⁰ =
3⁴¹⁺² - 3⁴⁴ + (2²ˣ²⁵ : 2⁴⁹ + 1)⁰ =
3⁴³ - 3⁴⁴ + (2⁵⁰ : 2⁴⁹ + 1)⁰ =
3⁴³ - 3⁴⁴ + (2⁵⁰⁻⁴⁹ + 1)⁰ =
3⁴³ - 3⁴⁴ + (2¹ + 1)⁰ =
3⁴³ - 3⁴⁴ + 3⁰ =
3⁴³ - 3⁴⁴ + 1
