Question

5. Efectuați: 46:23+{78 –3-[(15+7.5):5]–3.7}​

Answer 1

Răspuns: $\purple{\bf 46}$

Explicație pas cu pas:

$\bf 46:23+\{78 -3-[(15+7\cdot 5):5]-3\cdot7\}=$

$\bf 46:23+\{78 -3-[(15+35):5]-3\cdot7\}=$

$\bf 46:23+[78 -3-(50:5)-3\cdot7]=$

$\bf 46:23+(78 -3-10-3\cdot7)=$

$\bf 46:23+(78 -3-10-21)=$

$\bf 2+(75-10-21)=$

$\bf 2+(65-21)=$

$\bf 2+44=$

$\red{\boxed{\bf 46}}$
