Answer 1

Răspuns:

3×(n-8¹³:4¹⁷)=81⁸:27⁹

3[n-(2³)¹³:(2²)¹⁷]=(3⁴)⁸:(3³)⁹

3(n-2³ˣ¹³:2²ˣ¹⁷)=3⁴ˣ⁸:3³ˣ⁹

3(n-2³⁹:2³⁴)=3³²:3²⁷

3(n-2³⁹⁻³⁴)=3³²⁻²⁷

3(n-2⁵)=3⁵

n-2⁵=3⁵:3¹

n-2⁵=3⁵⁻¹

n=3⁴+2⁵

n=81+32

n=113

Answer 2

Răspuns: n = 113

Explicație pas cu pas:

Buna!

8 = 2³

4 = 2²

81 = 3⁴

27 = 3³

3 • (n - 8¹³ : 4¹⁷) = 81⁸ : 27⁹

3 • [n - (2³)¹³ : (2²)¹⁷] = (3⁴)⁸ : (3³)⁹

3 • (n - 2³ˣ¹³ : 2²ˣ¹⁷) = 3⁴ˣ⁸ : 3³ˣ⁹

3 • (n - 2³⁹ : 2³⁴) = 3³² : 3²⁷

3 • (n - 2³⁹⁻³⁴) = 3³²⁻²⁷

3 • (n - 2⁵) = 3⁵   |:3   (impartim toata relatia cu 3)

n - 2⁵ = 3⁵⁻¹

n - 2⁵ = 3⁴

n = 3⁴ + 2⁵

n = 81 + 32

n = 113
