oblicz!!!

(2^11*8*4^7*9x-8^10:4^8):4^7=(-3)^3

Answer 1

oblicz!!!

(2^11*8*4^7*9x-8^10:4^8):4^7=(-3)^3

[2¹¹*(2³)*(2²)⁷ * 9x - (2³)¹⁰ :(2²)⁸] : (2²)⁷ =(-3)³

[2¹¹*2³*2¹⁴*9x  - 2³⁰ : 2¹⁶] : 2¹⁴ = (-3)³

[2²⁸*9x - 2¹⁶]:2¹⁴= (-3)³

2¹⁵*(2⁵*9x - 1) : 2¹⁴ =(-3)³

2¹⁵: 2¹⁴*(2⁵*9x  -1 ) = (-3)³

2*(2⁵*9x -1 ) =  (-3)³

2*2⁵*9x - 2*1 = -27

2⁶*9x -2 = -27

2⁵*9x = -27 +2

2⁵*9x = -25

32*9x = -25

288 x = -25         /:288

       x = (-25): 288

       x = - 25/288
