Answer 3

a) 113 x (54+45+1)=113 x 100=11300

b) (36+62) x (117-17)=98 x 100=9800

Answer 4

a)54 x 113 + 45 x 113 + 113

 =113 x ( 45 + 54 + 1)

 =113 x 100

= 11300

  b)117 x ( 36 + 62) - 17 x ( 62 + 36 )

    = 117 x 98 - 17 x 98

    = 98 x ( 117 -17 )

     = 98 x 100

     = 9800

Kb với mk nhé!

Answer 5

a)=(54+45)x(113x3)
   =100x339

   =33900

b)=(117-17)x(62x2+36x2)

   =100x(124+72)

   =100x196

   =19600
