B) 203•456-203•306-50•203
C) 2017•2016-2016•17-2000•16

Answer 1

Răspuns:

a) 1996(1995+5) =1996*2000 =399200

b) 203 ( 456-306-50)=203*100= 20300

c) 2016 (2017-17) -32000= 2016*2000-32000 = 4032000- 32000 = 4000000

Answer 2

Răspuns:

A 1996×(5+1995)=1996×2000=3992000

B203×(456-306-50)=203×(150-50)=203×100=20300

C2016×(2017-17)-32000=2016×2000-32000=4032000-32000=4000000
