Question

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

Answer 1

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

= 792,81 x 0

= 0 

Answer 2

=(792,81×0,25+792,81×0,75)×(99-90-9) =(792,81×0,25+792,81×0,75)×0 =0

Answer 3

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

\(=\left(792,81\times\left(0,25+0,75\right)\right)\times\left(11\times9-10\times9-9\right)\)

\(=(792,81\times1)\times\left(9\times\left(11-10-9\right)\right)\)

\(=792,81\times9\times\left(-8\right)\)

\(=-57082,32\)
