=-13700

k mk nhé chúc bn học giỏi

a) ( -137 ) + ( + 52 ) x ( -137 ) + ( - 137 ) x ( + 47 )

=    ( - 137 ) x 1 + ( + 52 ) x ( -137 ) + ( -137 ) x ( + 47 )

=      ( - 137 ) x ( 1 + 52 + 47 )

=        ( - 137 ) x (  53 + 47 )

=         ( - 137 ) x 100

=            - 13700

Chúc bạn học giỏi !

Happy new year !

tk nha, mình đang âm

Sorry, lại nhầm

\(c,\left(\frac{-1}{6}+\frac{5}{-12}\right)+\frac{7}{12}\)

\(=-\frac{7}{12}+\frac{7}{12}\)

\(=0\)

sorry nha, mình ghi bị nhầm đó

giúp mình với

a] -567 + 113 - 113567 - 2011

   = -454 - 113567 - 2011

   = -114021 - 2011= -116032

B] -137 x [52 + 47+1]

    = -13700

C] 15 x [16 - 222] - 16 x [222 + 15] 

   = 15 x [-206] - 16 x 237

a)

\(34.86+68.37\)

\(=34.2.43+68.37\)

\(=68\left(43+37\right)=68.70=4760\)

b)

\(47.25+137.49+47.75-37.49\)

\(=47\left(25+75\right)+49\left(137-37\right)\)

34 . 86 + 68 . 37

= 34 . 2 . 43 + 68 . 37

= 68 . 43 + 68 . 37

= 68 . (43 + 37)

= 68 . 100

= 6800

47 . 25 + 137 . 49 + 47 . 75 - 37 . 49

= 47 . (25 + 75) + 49 . (137 - 37)

= 47 . 100 + 49 . 100

= 4700 + 4900

= 9600
