Question

Vă rog rapid dau coroană și puncte!​

Answer 1

$\it =3^{28}:3^{27}+27-1\cdot(729:243+27:9)=3^4+27-(3+3)=\\ \\ =81+27-6=102$

Answer 2

Răspuns:

9¹² –› (3²)¹² –› 3²⁴

(3³)¹ –› 3³ ; 18¹ –› 18

3⁵ –› 243; 3³ –› 27

3² –› 9; 3⁰ –› 1

– – – – – – – – – –

3²⁸ ÷ 3²⁴ + 3³ - 3⁰ × [729 ÷ 3⁵ + 3³ ÷ (3 × 3² - 18)]

3⁴ + 3³ - 3⁰ × [729 ÷ 243 + 27 ÷ (3 × 9 - 18)]

81 + 27 - 1 × [3 + 27 ÷ (27 - 18)]

81 + 27 - 1 × (3 + 27 ÷ 9) –› 81 + 27 - 1 × (3 + 3)

81 + 27 - 1 × 6 –› 81 + 27 - 6

108 - 6 –› 102
