b)|- 4 supra 5|-|9 supra 5|=

4.a)|1+1supra 6 |-|7supra 2 -2|
​

Answer 1

Răspuns:

Explicație pas cu pas:

a)|-31|+|-8|-|75|=  31 + 8 - 75 = -36

b)|25|-|47|+|-3|= 25 - 47 + 3 = -19

___________

a)|(-58)+|-4||:|-9|= |-58+4| : 9 =  |-54| : 9 = 54 : 9 = 6

b)||60|-|-15||:|-5|=|60- 15| : 5 = |45| : 5 = 45 : 5 = 9

_____________

a)|-7/2|+|3/2|= 7/2 + 3/2 = 10/2 = 5

b)|- 4/5|-|9/5|=4/5 - 9/5 = -5/5 = -1

_____________

a)|1+1/6|-|7/2 -2| = |7/6|-|7/2 -4/2| = 7/6 - 3/2 = 7/6 - 9/6 = -2/6 = -1/3
