25.(75-49)+75.|25-49|

 

Answer 1

\(25.\left(75-49\right)+75.\left|25-49\right|\)

\(=25.75-25.49+75.24\)

\(=25.75-25.49+25.3.24\)

\(=25.75-25.49+25.72\)

\(=25.\left(75-49+72\right)\)

\(=25.98\)

\(=2450\)

Answer 2

25 . (75 - 49) + 75 . |25 - 49|

= 25 . 26 + 75 . 24

= 25 . (26 + 24)

= 25 . 50

= 1250
