Answer 1

a.24x18+83x24-24

=24x18+24x(83-1)

=24x18+24x82

=24x(82+18)

=24x100=2400

b,162x6+3x162+162

=162x(6+3+1)

=162x10

=1620

mik làm đúng rồi đó

Answer 2

a, 24 x 18 +83 x24 -24

= 24 x ( 18+83-1) 

= 24 x100 = 2400

b, 162 x6 +3 x162 +162

= 162 x ( 6+3+1)

= 162 x10 = 1620

Answer 3

a) 24 x 18 + 83 x 24 - 24

= 24 x ( 18 + 83 - 1 )

= 24 x 100

= 2400

b) 162 x 6 + 3 x 162 + 162

= 162 x ( 6 + 3 + 1 )

= 162 x 10

= 1620

Answer 4

A)24*18+83*24-24

=(18+83)*24

=2424-24

=2400

B)162*6+3*162+162

=(6+3+162)*162

=171*162

=27702

Answer 5

a) 24 x 18 + 83 x 24 - 24

= 24 x (18 + 83 - 1)

= 24 x 100

= 2400

b) 162 x 6 + 3 x 162 + 162

   = 162 x (6 + 3 + 1)

   = 162 x 10 

   = 1620

Answer 6

A) 24 x 18 + 83 + 83 x 24 - 24

    = 24 x (18 + 83) - 24

    = 24 x 101 - 24

     = 24 x (101 - 1)

     = 24 x 100 = 2400

B) 162 x 6 + 3 x 162 + 162

    = 162 x (6 + 3) + 162

    = 162 x 9 + 162

    = 162 x (9 + 1)

    = 162 x 10 = 1620 

Answer 7

A) 24 x 18 + 83 x 24 -24

= 24 x 18 + 24 x (83-1)

= 24 x 18 + 24 x 82

= 24 x (82 + 180

= 24 X 100=2400

b)162 x 6 + 3 x 162 + 162

=162x(6+3+1)

=162x10

=1620
