Question

Efectuati operatiile: 1.75+{2 x 3+5,75+[3,75 x(1,35-0,35)+2,25]:3}:13,75
Care este ordinea efectuarii operatiilor?

Answer 1

Răspuns: $\color{red}\Large\boxed{\bf 2,75 }$

Explicație pas cu pas:

$\large\bf 1,75 + \{2 \cdot 3+5,75+[3,75 \cdot(1,35-0,35)+2,25]:3\}:13,75=$

$\large\bf 1,75 + [6+5,75+(3,75 \cdot 1+2,25):3]:13,75=$

$\large\bf 1,75 + [6+5,75+(3,75+2,25):3]:13,75=$

$\large\bf 1,75 + (6+5,75+6:3):13,75=$

$\large\bf 1,75 + (6+5,75+2):13,75=$

$\large\bf 1,75 + 13,75:13,75=$

$\large\bf 1,75 + 1=$

$\color{red}\Large\boxed{\bf 2,75 }$
