63 . (–25) + 25 . (–23)

= – 63 . 25 + 25 . (–23)

= 25. [–63 + (–23)]

= 25. (–86) = – (25.86) = –2150

63.(-25)+25.(-23)

=(-63).25+25.(-23) 

=25.[(-63)+(-23)]

=25.(-86)

=-2150  

63 . (-25) = (-63) . 25

=> 25 . ( -63 + 23 )

= 25 . -40

= -1000 

63 . (-25) + 25 . (-23)=63.-23.(-25)+25=63.-23.0=0

Học tốt nhé!

63 . 25 + 5 .63 + 63 . 14 + 33 . 63

= 63 . ( 25 + 5 + 14 + 33 ) 

= 63 . 77

= 4851

mk giải lun ạ

=63.(25+5.14+33)

=63.(25+70+33)

=63.128

=8064

\(63\cdot25+5\cdot63\cdot14+33\cdot63\)

\(=63\cdot25+70\cdot63+33\cdot63\)

\(=63\cdot\left(25+70+33\right)\)

\(=65\cdot128\)

\(=8320\)

63 . 25 + 5 . 63 .14 +33 .63

=63. ( 25 +5 +14 +33 )

=63 . 77

=4851

A: 63 * 0,007 + 63 * 0,002 + 63 * 0,001

=63 * ( 0,007 + 0,002 + 0,001 )

= 63 * 0,001

= 0,063

 ý B mình ko biết !

A : 63 x 0,007 + 63 x 0,02 + 63 x 0,001 = 0,063

B : 1/4 + 37 x 25 % + 0,25 x 62

= 1/4 + 37/4 + 31/2

= 19/2 + 31/2

= 25
