giup minh lamf nhaaaaaaaaaaaaaaaaaaaaaaaaa.Thank you very much

Answer 1

136 x 46 + 68 x 2 x 54

= 136 x 46 + 136 x 54

= 136 x (46 + 54)

= 136 x 100

= 13600

218 x 63 - 59 x 2 x 63

= 218 x 63 - 118 x 63

= 63 x (218 - 118)

= 63 x 100

= 6300

354 x 452 + 704 x 274

= 160008 + 192896

= 352904

668 x 182 - 334 x 164

= 334 x 2 x 182 - 334 x 164

= 334 x 364 - 334 x 164

= 334 x (364 - 164)

= 334 x 200

= 66800

#Học tốt!!!

Answer 2

136x46+68x2x54

=6256+7344

=13600

218x63-59x2x63

=13734-7434

=6300

354 x 452 + 704 x 274

=160008+192896

=352904

668 x 182 - 334 x164

=121576-54776
