Question

Vă pun poza că așa nu se înțelege ​

Answer 1

Răspuns:

Explicație pas cu pas:

=[ (²⁾5/2+5/4-3/4):5 +2/5]⁵

= [ (10/4+5/4-3/4):5 +2/5 ]⁵

=[ (15/4-3/4):5+2/5]⁵

= (12/4:5+2/5)⁵

= (12/20+⁴⁾2/5)⁵

= (12/20+8/20)⁵

= (20/20)⁵

= 1⁵

=1

a=1

-

= (²⁾7/3+³⁾7/2) :7/12- [ 10/3⁽³*3⁽³/1- 3 ⁽³*10/3⁽³ +3/2:1/4]

= (14/6+21/6) *12/7 - ( 10- 10 +3/2*4/1)

= 35⁽⁷/6⁽⁶*12⁽⁶/7⁽⁷ - ( 3/2⁽²*4⁽²/1)

= 10 - 3*2

= 10-6

=4

b=4
