1.Tính:

a)1.135.2.18+54-3.5

b)2.100.754.7878-4567

Answer 1

a = 4899

b=1187997833

Answer 2

1 x 135 x 2 x 18 + 54 - 3 x 5 

= 135 x 2 x 18 + 54 - 3 x 5

= 270 x 18 + 54 - 3 x 5 

= 4860 + 54 - 15

= 4915 - 15

= 4900

b) 2 x 100 x 754 x 7878 - 4567

= 200 x 754 x 7878 - 4567

= 150800 x 7878 - 4567

= 1188002400 - 4567

= 1187997833
