Có 37.(29-23)-29.(37-23)

=(37.29-37.23)-(29.37-29.23)

=37.29-37.23 - 29.37+29.23

=(37.29-29.37)-37.23+29.23

=0-184= -184

Ko biết mk lm đúng ko nếu sai thì mk xin lỗi nha

chịu

Bằng 0 nha k k t i c k

\(37.\left(29-23\right)-29\left(37-23\right)\)

=\([\left(37.29\right)-\left(37.23\right)]-[\left(29.37\right)-\left(29.23\right)]\)
