Efectuati calculele, respectand ordinea efectuarii operatiilor​

Answer 1

Răspuns:

a) 3×(-6)+6×(-3)+35

=(-18)+(-18)+35

=(-36)+35

= -1

b)-15:(-6+1)-24:(-8+14)

=-15:(-5)-24:6

=3-4

= -1

c)-1+2×[-3+4×(-5+6)]

=-1+2×(-3+4×1)

=-1+2×(-3+4)

=-1+2×1

=-1+2

=1

d)[(-6+7×2):10+9]×3

=[(-6+14):10+9]×3

=(8:10+9)×3

=(0,8+9)×3

=9,8×3

=29,4

e) [-4+(-3+91÷7):(-5)]:(-2)

=[-4+(-3+13):(-5)]:(-2)

=[(-4+10:(-5)]:(-2)

=(-4+(-2) ):(-2)

= -6:(-2)

=3

f)

${2}^{ 3} = 8$

$- {3}^{2} = 9$

8+9+(-2)×(+3)

=17+(-6)

=11
