Question

4*18*25+(142*12+142*18)=

Answer 1

= 6060

Answer 2

4 x 18 x 25 + (142 x 12 + 142 x 18)

= (4 x 25) x 18 + (142 x (12 + 18))

= 100 x 18 + (142 x 30)

= 1800 + 4260

= 6060

Answer 3

4*18*25+(142*12+142*18)=

4×25×18+[142×(12+18)]

=100×18+[142×30]

=1800+4260

=6060

Answer 4

4x18x25+(142x2+142x18)=

=4x25x18+(142x2+142x18)

=100x18+(142x2+142x18)

=100x18+142x2+142x18

=1800+142x2+142x18

=142x2+142x18+1800

=142x(2+18)+1800

=142x20+1800

=2840+1800

=4640
