Chúc bạn học tốt!

G=3

bn có cần lời giải ko?

để G lớn nhất thì :

\(|4x-1|\);\(|xy-3|\)nhỏ nhất và bằng 0

=> 4x-1 =0                                                        1/4 . y-3=0

          x= (1+0) :4                                                y=(0+3) :1/4

         x=1/4   =>x=1/4                                         y=12

=> G= 3 - \(|4x-1|\)-  \(|xy-3|\)

=> G=3-0-0=3

vậy maxG=3
