Question

(4x+1)(12-1)(3x+2)(x+1)=4

Answer 1

<=>(4x+1)(12-1)(3x+2)(x+1)=11(x+1)(3x+2)(4x+1)

=> 11(x+1)(3x+2)(4x+1)=2^2

=>x=61*11^(1/3)/(4*3^(11/6)*(8777*căn bậc hai(3)+12194.7974152915)^(1/3))+(8777*căn bậc hai(3)+12194.7974152915)^(1/3)/(4*3^(13/6)*11^(1/3))-23/36

Answer 2

Cho hỏi 12x - 1 hay 12 - 1 

Answer 3

thắng : chắc là (12x-1) nếu là (12x-1) thì tui sai :(
