Question

[|8-3*|-2||+13-5*|-2||]:|-5|

Answer 1

Răspuns:

[|8-3·|-2||+I13-5·|-2|I] : |-5| = 1

Explicație pas cu pas:

[|8-3·|-2||+I13-5·|-2|I] : |-5| = ?

I-2I = 2

I-5I = 5

[|8-3·|-2|| + I13-5·|-2|I] : |-5| = [ I 8-3·2 I + I13-5·2I] :5 =

= [I8-6I + I13-10I] : 5 = [I2I + I3I] :5 = (2+3):5 = 5:5 = 1

Answer 2

$\big(\left|8-3\cdot \left|-2\right|\right|+13-5\cdot \left|-2\right|\big) :\left|-5\right| =\\ \\ =\big(\left|8-3\cdot 2\right|+13-5\cdot 2\big) :5 \\ \\ =\big(\left|8-6\right|+13-10\big) :5\\ \\ =(2+13-10) :5\\ \\ =(2+3):5\\ \\ = 5:5\\ \\ = 1$
