Answer 1

Răspuns:

0,5+8·[1/4+(²⁾7/12-1/24):(8×3+2)/3]=

5/10+8·[1/4+(14/24-1/24):26/3]=

5/10+8·(1/4+13/24:26/3)=

5/10+8·(1/4+13/24·3/26)=

5/10+8·(⁴⁾1/4+1/16)=

5/10+8·(4/16+1/16)=

5/10+8·5/16=

5/10+⁵⁾5/2=

5/10+25/10=

30/10=

Answer 2

Răspuns:

Explicație pas cu pas:

= 0,5+8*[1/4+(²⁾7/12-1/24): 26/3]

=0,5+8*[1/4+(14/24-1/24):26/3]

= 0,5 +8*[1/4+(13⁽¹³/24⁽⁸ *3⁽⁸/26¹³⁾ ]

= 0,5+8⁽⁸ *(⁴⁾1/4+1/16)

= 0,5+8*( 4/16+1/16)

=0,5+8⁸⁾*5/16⁸⁾

=0,5+ 5/2

= 5/10+⁵⁾5/2

=5/10+25/10

= 30/10

= 3
