147 x 91 x 147 x 909
= ( 147 x 91 ) x ( 147 x 909 )
= 13377 x 133623
= 1787474871
2016 x 419 - 2016 x 329
= ( 419 - 329 ) x 2016
= 100 x 2016
= 201600
147 x 91 x 147 x 909
= 13377 x 133623
= 1787474871
2016 x 429 - 2016 x 329
= 2016 x ( 429 - 329 )
= 2016 x 100
= 201600
\(147.91+147.909=147.\left(91+909\right)=147.1000=147000\)
\(2016.429-2016.329=2016.\left(429-329\right)=2016.100=201600\)
147 x 91 x 147 x 909 2016 x 429 - 2016 x 329
= 147 x ( 91 x 909 ) = 2016 x ( 429 - 329 )
= 147 x 82719 = 2016 x 100
= 12159693 = 2016 x 100
