Answer 1

Răspuns:

Formule folosite: a⁰ = 1

0ⁿ = 0

a¹ = a

Explicație pas cu pas:

11²-11¹+11⁰= 121 - 11 + 1 = 111

5²-2⁵+19⁰= 25 - 32 + 1 = - 6

0¹³+13¹+13⁰= 0 + 13 + 1 = 14

(23-3²-23⁰)²-13²= (23 - 9 - 1)² - 169 = 13² - 169 = 169 - 169 = 0

(34:17)²-2013⁰=​ 2² - 1 = 4 - 1 = 3

Answer 2

Răspuns:

3² + 13⁰ - 11⁰ + 11¹⁰ + 4 = 13 + 11¹⁰

11² - 11¹ + 11⁰ = 111

5² - 2⁵ + 19⁰ = -6

0¹³ + 13¹ + 13⁰ = 14

(23 - 3² - 23⁰)² - 13² = 0

(34:17)² - 2013⁰ =​ 3

Explicație pas cu pas:

3² + 13⁰ - 11⁰ + 11¹⁰ + 4 = 9 + 1 - 1 + 11¹⁰ + 4 = 13 + 11¹⁰

11² - 11¹ + 11⁰ = 121 - 11 + 1 = 111

5² - 2⁵ + 19⁰ = 25 - 32 + 1 = -6

0¹³ + 13¹ + 13⁰ = 0 + 13 + 1 = 14

(23 - 3² - 23⁰)² - 13² = (23 - 9 - 1)² - 13² = 13² - 13² = 0

(34:17)² - 2013⁰ =​ 2² - 1 = 4 - 1 = 3
