Answer 1

\(\left(792,81\times0,25+792,81\times0,75\right)\times\left(11\times9-900\times0,1-9\right)\)

\(=\left[792,81\times\left(0,25+0,75\right)\right]\times\left(1089-90-9\right)\)

\(=\left(792,81\times1\right)\times990\)

\(=792,81\times990\)

\(=784881,9\)

Answer 2

ta có :

(792,81 x 0,25 + 792,81 x 0,75 ) x ( 11 x 9 - 900 x 0,1 - 9 )

=> [ 792,81 . ( 0,25 + 0,75 ) ] x ( 99 - 90 - 9 )

=> [ 792,81 . 1 ] x ( 9 - 9)

=> 792,81 x 0

= 0

Answer 3

đúng 100%

Answer 4

(792,81 x 0,25 + 792,81 x 0,75 ) x ( 11 x 9 - 900 x 0,1 - 9 )

= [ 792,81 . ( 0,25 + 0,75 ) ] x ( 99 - 90 - 9 )

= [ 792,81 . 1 ] x ( 9 - 9)

= 792,81 x 0

= 0
