Question

Вычисли группируя множители.
5*7*2=
8*5*9=
2*6*50=
7*20*5=
25*5*4=
10*7*20=

Answer 1

5*7*2=(5*2)*7=10*7=70
8*5*9=(8*5)*9=40*9=360
2*6*50=(2*50)*6=100*6=600
7*20*5=7*(20*5)=7*100=700
25*5*4=(25*4)*5=100*5=500
10*7*20=(10*20)*7=200*7=1400

Answer 2

(5*2)*7=70. (5*8)*9=360. (2*50)*6=600. (20*5)*7=700. (25*4)*5=500. (10*20)*7=1400
