= (-98) . (-245) - 246 .98
= 98 . 245 - 246 .98
= 98 . ( 245- 246 )
= 98 . (-1)
= -98
tích nha mọi người
(-98)x(1 - 246) - 246 x 98
=(-98)x(-245)-246x98
=98x245-246x98
=98x(245-246)
=98x(-1)
=-98
![](https://rs.olm.vn/images/avt/0.png?1311)
( -98 ) x ( 1 - 246 ) - 246 x 98
= -98 x ( 1 - 246 + 246 )
= -98 x 1
= -98
\(\left(-98\right).\left(1-246\right)-246.98\)
\(=-98.\left(1-246+246\right)\)
\(=-98.1\)
\(=-98\)

= (-98 + 98*246) - 246*98
=-98 + (98*246 - 246*98)
=-98 + (98*246 - 98*246)
= -98

- 98 * ( 1 - 246 ) - 246 * 98
= - 98 * ( - 245 ) - 24108
= 24010 - 24108
= - 98

a, (-4).(+125).(-25).(-6).(-8) =(-4).125.(-25).(-6).(-8)=(-500).(-25).(-6).(-8)=12500.(-6).(-8)=(-75000).(-8)=600000
b,(-98).(1-246)-246.98=(-98).(-245)-24108=24010-24108=-98
k mk nha!!!!

a ) ( -4 ) . ( +125 ) . ( -25 ) . ( -6 ) . ( -8 )
=[(-4).(-25)].[125.(-8)].-6
=[100.(-1000)].(-6)
=-100000.(-6)
=60000
b ) ( -98 ) . ( 1 - 246 ) - 246 . 98
(-98)x(1 - 246)- 246 x 98
= ( - 98 ) x ( -245 ) - 4508
= 24010 - 4508
= 19502
Tick cho mình nha!
