Question

Calculaţi 0,5+8 •[1supra4+(7 supra 12-1 supra24):8 inttegi 2 supra 3

Answer 1

0,5 + 8 × [1/4 + (7/12 - 1/24) : 8 si2/3] =

= 1/2 + 8 × [1/4 + (14/24 - 1/24) : 26/3] =

= 1/2 + 8 × (1/4 + 13/24 : 26/3) =

= 1/2 + 8 × (1/4 + 13/24 × 3/26) =

= 1/2 + 8 × (1/4 + 1/8 × 1/2) =

= 1/2 + 8 × (1/4 + 1/16) =

= 1/2 + 8 × (4/16 + 1/16) =

= 1/2 + 8 × 5/16 =

= 1/2 + 5/2 =

= 6/2 =

= 3
