TÍNH NHanh

(532*7-66*11)*(532*77+266)

 

Answer 1

= 948 * 113 + 43 * 113 + 113 * 1

= (948 + 43 + 1) * 113

= 992 * 113

= 112096

Answer 2

\(948.113+43.113+113.1\)

\(=113.\left(948+43+1\right)\)

\(=113.992=112096\)

Answer 3

=113*(948+43+1)

=113*992

=112096

Answer 4

948x113+43x113+113x9

=(948+43+9)x113

=1000x113

=113000
