Question

9. Calculează:
a) |-4| + |5| + |-11|;
d) |28|: |-14|+ |8|;
b) -|27|- |- 13| + |16|;
e) (|-2|)laputera a 8:(|2|)la putere a 6-(|-2|)
c) |-14| · |-2|- |-8|;
f) (|5-2|):|-3|-|-3|.
​

Answer 1

Răspuns:

a) |-4|+|5|+|-11|=20;

4 + 5 + 11=20

9 +11=20

20

b) |-27|-|-13|+|16|=30;

27- 13 +16=30

14 +16=30

30

d)|28|:|-14|+|8|=10;

28: 14 +8 =10

2 +8=10

10

e) (|-2|)8:(|2|)6-(|2|)2=16;

(2)8:(2)6-(2)2=16

(2)8-6+2=16

(2)2+2=16

(2)4=16

16

Answer 2

Răspuns:

Explicație pas cu pas:

a) |-4| + |5| + |-11|=4+5+11=20

d) |28|: |-14|+ |8|=28:14+2+8=10

b) -|27|- |- 13| + |16|=-27-13+16=-24

e) (|-2|)^ 8:(|2|)^6 -(|-2|) =2^8:(2^6-2)=2^8:2(32-1))=2^7:31=128/31

c) |-14| · |-2|- |-8|=-(14·16)=-224

f) (|5-2|):|-3|-|-3|=3:3-3=1-3=-2
