25,6 x 23,6 + 49,5 x 51,2 + 25,6 =

Answer 1

25,6 x 23,6 + 49,5 x 51,2 + 25,6

= 25,6 x 23,6 + 49,5 x 2 x 25,6 + 25,6

= 25,6 x ( 23,6 + 49,5 x 2 + 1)

= 25,6 x 123,6

= 3 164, 16

Answer 2

\(25,6.23,6+49,5.51,2+25,6\)

\(=25,6.\left(23,6+1\right)+2534,4\)

\(=25,6.24,6+2534,4\)

\(=629,76+2534,4\)

\(=3164,16\)

đề nó cứ sao sao ấy
