Question

9 . Tính :

x = 27 x 38  + 62 x 27 - 27 x 90

Answer 1

\(x=27.38+62.27-27.90\)

\(x=27.\left(38+62-90\right)\)

\(x=27.10\)

\(=270\)

Answer 2

x = 27*(38+62-90)

x = 27*10

x = 270

Answer 3

x = 27 x 38  + 62 x 27 - 27 x 90 .

x = 27 . ( 38 + 62 - 90 )

x = 27 . 10

x = 270 

Answer 4
