Question

\(a.25\) x \(432\) x \(4\) \(=\)

\(b.456 \) x \(200-\) \(456\) x \(100=\)

Answer 1

`a)25xx532xx4`

`=(25xx4)xx432`

`=432xx100=43200`

`b)456xx200-456xx100`

`=456xx(200-100)`

`=456xx100=45600`

Answer 2

\(a,25\times432\times4=25\times4\times432=100\times432=4320\\ b,456\times200-456\times100=456\times\left(200-100\right)=456\times100=45600\)

Answer 3

`25 xx 432 xx 4 = (25xx4 ) xx 432 = 100 xx 432 = 43200`

 

`456 xx200 - 456 xx 100 = 456 xx ( 200 - 100 ) = 456 xx 100 = 45600`
