Question

va rog frumos
imi trebuie urgent​

Answer 1

Explicație pas cu pas:

a)

6(3+30:3)=

=6(3+10)=

=6*13

=78

b)

11+2(15*2-20)=

=11+2(30-20)=

=11+2*10=

=11+20=

=31

c)

(4*11-4)*15=

=(44-4)*15=

=40*15=

=600

d)

4+2[2+3(5+5:5)]=

=4+2[2+3(5+1)]=

=4+2(2+3*6)=

=4+2(2+18)=

=4+2*20=

=4+40=

=44

e)

[5+(120-3*40):99]+15=

= [5+(120-120):99]+15=

= (5+0:99)+15=

=(5+0)+15=

=5+15=

=20

f)

450:{6+[9+(9+9:9)]}=

=450:{6+[9+(9+1)]}=

=450:[6+(9+10)]=

=450:(6+19)=

=450:25=

=18

Answer 2

Răspuns:

a)6(3+30:3)=6(3+10)=6×13=78 b)11+2(15×2-20)=11+2(30-20)=11+2×10=11+20 =31

c)(4×11-4)×15=(44-4)15=40×15=600

d)4+2[2+3 (5+5:5)]=

=4+2[2+3(5+1)]=

=4+2(2+3×6)=

=4+2(2+18)=

=4+2×20=

=4+40=

=44

e)[5+(120-3×40):99]+15=

=[5+(120-120):99]+15=

=(5+0:99)+15=

=5+15=

=20

f)450:{6+[9+(9+9:9)]}=

=450:{6+[9+(9+1)]}=

=450:[6+(9+10)]=

=450:(6+19)=

=450:25=

=18
