293 x 45 + 293 x 50 x 5
= 293 x 45 + 293 x 250
= 293 x ( 45 + 250 )
= 293 x 295
= 86435
293 x 45 + 293 x 50 x 5
= 293 x ( 45 + 50 + 5 )
= 293 x 100
= 29300
k minh nha
293 x 45 + 293 x 50 x 5
=293 x (45 + 50 + 5)
=293 x 100
=29300
293*45+293*50*5
=293*45+50*5
=293*295
=86435
293 x (45+50) x 5
293x 95 x5
27835 x5
139175
=293*(45+50*5)
=293*(45+250)
=293*295
=86435
293 x 45 + 293 x 50 x 5
