Question

scrieti succesorul numarului a, unde:a) a={(150-5x20):50+12x[13+7x(473:43-2x5)]}x4+36; b) a=44+3x(639-8x[32+2x(210-10971:53)]}; c)a=12+2x[(31-5x6)-1]+56:14

Answer 1

a)

a = { ( 150 - 5 × 20 ) : 50 + 12 × [ 13 + 7 × ( 473 : 43 - 2 × 5 ) ] } × 4 + 36

a = { ( 150 - 100 ) : 50 + 12 × [ 13 + 7 × ( 11 - 10 ) ] } × 4 + 36

a = [ 50 : 50 + 12 × ( 13 + 7 × 1 ) ] × 4 + 36

a = [ 1 + 12 × ( 13 + 7 ) ] × 4 + 36

a = ( 1 + 12 × 20 ) × 4 + 36

a = ( 1 + 240 ) × 4 + 36

a = 241 × 4 + 36

a = 964 + 36

a = 1 000

1 001 → succesorul lui a ( vecinul mai mare cu o unitate )

b)

a = 44 + 3 × { 639 - 8 × [ 32 + 2 × ( 210 - 10 971 : 53 ) ] }

a = 44 + 3 × { 639 - 8 × [ 32 + 2 × ( 210 - 207 ) ] }

a = 44 + 3 × [ 639 - 8 × ( 32 + 2 × 3 ) ]

a = 44 + 3 × ( 639 - 8 × 38 )

a = 44 + 3 × ( 639 - 304 )

a = 44 + 3 × 335

a = 44 + 1 005

a = 1 049

1 050 → succesorul numarului a

c)

a = 12 + 2 × [ ( 31 - 5 × 6 ) - 1 ] + 56 : 14

a = 12 + 2 × [ ( 31 - 30 ) - 1 ] + 4

a = 12 + 2 × ( 1 - 1 ) + 4

a = 12 + 2 × 0 + 4

a = 16

17 → succesorul numarului a
