812-x:11=46

=> x:11=766

=> x=8426

Vậy x=8426

8426 nha bạn

812 - x : 11 = 46

         x : 11 = 812 - 46

         x : 11 =     766

         x        = 766 x 11 = 8426

\(812-x:11=46\)

          \(-x:11=46-812\)

           \(-x:11=-766\)

                 \(-x=\left(-766\right)\times11\)

                 \(-x=-8426\)

                     \(x=8426\)

812 - x : 11 = 46

=> x : 11 = 812 - 46

=> x : 11 = 766

=> x = 766 * 11

=> x = 8426

Đáp số : x = 8427

can on cac ban

\(812-x:11=46\)

\(x:11=812-46\)

\(x:11=766\)

\(x=766x11\)

\(x=8426\)

Vậy x=8426

812 - x : 11 = 46

812 - x        = 46 x 11

812 - x        = 506

         x        = 812 - 506

         x        = 306

\(812-x:11=46\)

              \(x:11=812-46\)

              \(x:11=766\)

              \(x=766\cdot11\)

              \(x=8426\)

dấu chấm là dấu nhân đấy

ko bik

x /  11=812-46=766

x=766 x 11 =8426

812x5+812x7-812x2

=812x(5+7-2)

=812x10

=8120

   812 x 5 + 812 x 7 - 812 x 2

= 812 x ( 5 + 7 - 2 )

= 812 x  10

= 8120

Chúc bn hok tốt !

   812 x 5 + 812 x 7 - 812 x 2
= 812 x ( 5 + 7 - 2 )
= 812 x  10
= 8120

a) =(-4).(-25).125.(-8).(-11)

     = 100.(-1000).(-11) 

     = (-100000).(-11)

      = 1100000

b) =(-823)+823 . 812-812.823

    =(-823)+(823.812-812.823)

    = (-823) +0

    =-823

  k giùm mình nha!

  Hok tốt!

a) ( -4)×125×(-25)×(-11)×(-8)

 = [ -4 x ( -25 ) ] x ( -8 x 125 ) x ( -11 )

= 100 x ( -1000) x ( -11 )

= 1100000

b) (-823)× ( 1-812)-812×823

 = 823 ( 812-1) - 812 x 823

= (823 x 812 - 812 x 823) - 823

= -823

a, \(\left(-4\right).125.\left(-25\right).\left(-11\right).\left(-8\right)\)

\(=\left[\left(-4\right).125\right].\left[\left(-25\right).\left(-8\right)\right].\left(-11\right)\)

\(=\left(-500\right).200.\left(-11\right)\)

\(=\left(-100000\right).\left(-11\right)\)

\(=1100000\)

b, \(\left(-823\right).\left(1-812\right)-812.823\)

\(=\left(-823\right).\left(-811\right)-812.823\)

\(=823.811-812.823\)

\(=823.\left(811-812\right)\)

\(=823.\left(-1\right)\)

\(=-823\)
