Calculati:
a)50-40:[11-(256+44):100]
b)3•16+{7•[6-(4+2•3):5]-8}:10​

Answer 1

Răspuns:

a)

50-40:[11-(256+44):100]

50-40:(11-300:100)

50-40:(11-3)=

50-40:8=

50-5=45

b)

3•16+{7•[6-(4+2•3):5]-8}:10

48+{7x[6-(4+6):5]-8}:10

48+[7x(6-10:5)-8]:10

48+[7x(6-2)-8]:10

48+(7x4-8):10

48+(28-8):10

48+20:10

48+2=50
