a=[(5/2+5/4-3/4):5+2/5]totul la puterea a cincea și b=(2 1/3+3 1/2):7/12-[3 1/3:1/3-3:3/10+3/2:(1/2)la puterea adoua] va rooogggg :}}​

Answer 1

Răspuns:

Explicație pas cu pas:

-

{[( 5/2+5/4-3/4) :5 +2/5}⁵=

{[ (²⁾5/2+5/4-3/4 ) :5 +2/5} ⁵=

{[( 10/4+5/4-3/4 ) :5+2/5 }⁵=

[( 10+5-3)/4 ) :5+2/5]⁵=

(12/4:5+2/5)⁵=

(3:5+2/5)⁵=

(0,6+2/5)⁵=

(6/10+²⁾2/5)⁵=

[(6+4)/10)⁵=

(10/10)⁵=

1⁵=1

-

(2¹/₃+3¹/₂):7/12-[3¹/₃: 1/3-3:3/10+3/2:(1/2) ²=

(²⁾7/3+³⁾7/2):7/12 - [10/3-3⁽³ *10/ ⁽³3+ 3/2:1/4=

(14 /6+21/6)*12/7- [10/3-10 +3/2*4²⁾=

35⁷⁾/6*12⁶⁾/7 -[10-10+6)=

10-6=4
