Explicație pas cu pas:

= (1+2*2/1+3*3/1)*3/2-20

= (1+4+9)*3/2-20

=14⁽²*3/2⁽²-20

=7*3-20

=21-20

=1

-

= 1/2:( ²⁾1/5-1/10)-7/3*3/14

=1/2:( 2/10-1/10 ) -7⁽⁷/3⁽³*3⁽³/14⁽⁷

=1/2*10-1/2

=²⁾5-1/2

=10/2-1/2

=9/2

-

= ( 17⁽¹⁷/9⁽⁹*9⁽⁹/17⁽¹⁷)+2*(7/2-1/3⁽³*15⁽³/2)

= 1 + 2*( 7/2-5/2)

= 1+2*(2/2)

=1+2*1

=1+2

=3

-

=( 13/5-7⁽⁷/3⁽³*6⁽³/7⁽⁷) *10/7+1/7

= (13/5 -⁵⁾2)*10/7+1/7

=(13/5-10/5)*10/7+1/7

=3/5⁽⁵*10⁽⁵/7+1/7

=6/7+1/7

= 7/7

=1

-

= 10-40/3 :( 16/3-13/3)*( 7/5-4⁽²/15⁽³*3⁽³/2⁽²)*3/20

=10-40/3:3/13 *( 7/5 - 2/5)*3/20

=10-40/3*(3/3*5/5)*3/20

=10- 40⁽²⁰/3⁽³*1*3⁽³/20⁽²⁰

=10-2

=8

-

=[ 1/2+3*( 33⁽¹¹/4⁽²*10⁽²/11⁽¹¹ -1/2 ) ]*2/43+1

[1/2+3*( 15/2-1/2)*2/43+1

=1/2+3*( 14/2)*2/43+1

= (1/2+42/2)*2/43+1

=43⁽⁴³/2⁽²*2⁽²/43⁽³+1

=1+1

=2
