Question

tinh bang cach thuan tien nhat:(198,08 x 23,56 + 165,9 : 27) x (25,07 x 3 - 75,21) + 8,8 

Answer 1

\(\left(198,08\times23,56+165,9:27\right)\times\left(25,07\times3-75,21\right)+8,8\\ =\left(198,08\times23,56+165,9:27\right)\times\left(75,21-75,21\right)+8,8\\ =\left(198,08\times23,56+165,9:27\right)\times0+8,8\\ =0+8,8\\ =8,8\)

Answer 2

(198,08×23,56+ 165,9:27) × (25,07×3−75,21)+ 8,8

= (198,08 × 23,56 + 165,9 : 27) × (75,21 − 75,21) + 8,8

= (198,08× 23,56 +165,9:27) × 0 + 8,8

= 0+8,8

= 8,8

Answer 3

(198,08×23,56 + 165,9 : 27)×(25,07×3 − 75,21) + 8,8

= (198,08×23,56 + 165,9 : 27)×(75,21 − 75,21) + 8,8

= (198,08×23,56 + 165,9 : 27)×0 + 8,8

= 0 + 8,8

= 8,8
