Question

Se dau numerele a=8+3x[60+24:(8-4:2)]:6 si b=216:2-9x(16:2+219:73. Calculati valoarea numarului n=2x(a+b)

Answer 1

Explicație pas cu pas:

a=8+3×[60+24:(8-4:2)]:6=

=8+3×(60+24:6):6=

=8+3×(60+4):6=

=8+3×64:6=

=8+192:6=

=8+32=

=40

b=216:2-9×(16:2+219:73)

=108-9×(8+3)

=108-9×11

=108-99

=9

n=2×(a+b)

n=2×(40+9)

=2×49

=98

Answer 2

La mulți ani, Daria!

Răspuns:  n = 98

Explicație pas cu pas:

a = 8 + 3 × [ 60 + 24 : ( 8 - 4 : 2)] : 6

a = 8 + 3 × [ 60 + 24 : ( 8 - 2)] : 6

a = 8 + 3 × ( 60 + 24 : 6 ) : 6

a = 8 + 3 × ( 60 + 4 ) : 6

a = 8 + 3 × 64 : 6

a = 8 + 192 : 6

a = 8 + 32

a = 40

----------------------------------

b = 216 : 2 - 9 × (16:2 + 219:73 )

b = 108 - 9 × ( 8 + 3 )

b = 108 - 9 × 11

b = 108 - 99

b = 9

n = 2 × ( a + b )

n = 2 × ( 40 + 9)

n = 2 × 49

n = 98
